Gas exchange in different animals | Biology for All | FuseSchool
Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals have evolved different mechanisms for carrying out gaseous exchange. The most important thing is to create a large surface area, the bigger the surface area the faster diffusion of the gases can occur. Secondly they all have a good blood supply. You want to get oxygen into the blood and carbon dioxide out as quickly as possible so the blood travels very close to the exchange surface to once again maximise diffusion.

Alveoli: Gas Exchange
Revision notes and practice question for gas exchange: https://www.tes.com/teaching-resource/gas-exchange-11804216 Follow me on Instagram: https://www.instagram.com/sciencesauce_online/ Twitter: https://twitter.com/science_sauce Facebook: https://facebook.com/sciencesauceonline/ The alveoli ("many alveoli", "one alveolus") are the sites of gas exchange in the lungs. They are tiny air sacks sometimes described as being cauliflower-shaped. Oxygen diffuses across the lining of the alveoli and blood capillaries into and into red blood cells. Carbon dioxide diffuses from the blood to the alveoli. A concentration gradient is maintained by breathing as well as blood flow. The main adaptation of the gas exchange surface are: 1. Large surface area 2. Thin wall 3. Moist lining 4. Good blood supply 5. Good ventilation

Exchange surfaces (an overview)
First in the series of videos on mammalian exchange (OCR F211 Module 2: Exchange and Transport), specifically the Lungs. Here, I just talk about why exchange surfaces are needed and what makes a good exchange surface. All organisms need things from the environment (glucose, oxygen etc) but also need to remove their waste products (carbon dioxide, water etc). So all organisms need to exchange these things with the environment. For small organisms (such as single-celled ones) they can do this by diffusion alone. As organisms get bigger, with more cells, I discuss why, as the surface area to volume ratio reduces, diffusion is not adequate to exchange for all the cells of the organism. Therefore specialised exchange surfaces are needed. Finally, before we get started on the lungs, we go through the main features of specialised exchange surfaces: high surface area, thin barriers and ways to maintain a steep concentration gradient. Detailed discussion on the lungs follows (subscribe not to miss it!)

What Would Happen If Humans Tried To Land On Jupiter
The best way to explore a new world is to land on it. That's why humans have sent spacecraft to the Moon, Venus, Mars, Saturn's moon, Titan, and more. But there are a few places in the solar system we will never understand as well as we'd like. One of them is Jupiter. Jupiter is made of mostly hydrogen and helium gas. So, trying to land on it would be like trying to land on a cloud here on Earth. There's no outer crust to break your fall on Jupiter. Just an endless stretch of atmosphere. The big question, then, is: Could you fall through one end of Jupiter and out the other? It turns out, you wouldn't even make it halfway. Here’s what would happen if you tried to land on Jupiter. *It's important to note that we feature the Lunar Lander for the first half of the descent. In reality, the Lunar Lander is relatively delicate compared to, say, NASA's Orion spacecraft. Therefore, the Lunar Lander would not be used for a mission to land on any world that contains an atmosphere, including Jupiter. However, any spacecraft, no matter how robust, would not survive for long in Jupiter, so the Lunar Lander is as good of a choice as any for this hypothetical scenario. First things first, Jupiter's atmosphere has no oxygen. So make sure you bring plenty with you to breathe. The next problem is the scorching temperatures. So pack an air conditioner. Now, you're ready for a journey of epic proportions. For scale, here's how many Earths you could stack from Jupiter's center. As you enter the top of the atmosphere, you're be traveling at 110,000 mph under the pull of Jupiter's gravity. But brace yourself. You'll quickly hit the denser atmosphere below, which will hit you like a wall. It won't be enough to stop you, though. After about 3 minutes you'll reach the cloud tops 155 miles down. Here, you'll experience the full brunt of Jupiter's rotation. Jupiter is the fastest rotating planet in our solar system. One day lasts about 9.5 Earth hours. This creates powerful winds that can whip around the planet at more than 300 mph. About 75 miles below the clouds, you reach the limit of human exploration. The Galileo probe made it this far when it dove into Jupiter's atmosphere in 1995. It only lasted 58 minutes before losing contact and was eventually destroyed by the crushing pressures. Down here, the pressure is nearly 100 times what it is at Earth's surface.  And you won't be able to see anything, so you'll have to rely on instruments to explore your surroundings. By 430 miles down, the pressure is 1,150 times higher. You might survive down here if you were in a spacecraft built like the Trieste submarine — the deepest diving submarine on Earth. Any deeper and the pressure and temperature will be too great for a spacecraft to endure. However, let's say you could find a way to descend even farther. You will uncover some of Jupiter’s grandest mysteries.But, sadly, you'll have no way to tell anyone. Jupiter's deep atmosphere absorbs radio waves, so you'll be shut off from the outside world— unable to communicate. Once you've reached 2,500 miles down, the temperature is 6,100 ºF.  That's hot enough to melt tungsten, the metal with the highest melting point in the Universe. At this point, you will have been falling for at least 12 hours. And you won't even be halfway through. At 13,000 miles down, you reach Jupiter's innermost layer. Here the pressure is 2 million times stronger than at Earth's surface. And the temperature is hotter than the surface of the sun. These conditions are so extreme they change the chemistry of the hydrogen around you. Hydrogen molecules are forced so close together that their electrons break lose, forming an unusual substance called metallic hydrogen. Metallic hydrogen is highly reflective. So, if you tried using lights to see down here it would be impossible. And it's as dense as a rock. So, as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.  Eventually, that buoyancy will shoot you back up until gravity pulls you back down, sort of like a yo-yo. And when those two forces equal, you'll be left free-floating in mid-Jupiter, unable to move up or down, and no way to escape! Suffice it say, trying to land on Jupiter is a bad idea. We may never see what's beneath those majestic clouds. But we can still study and admire this mysterious planet from afar.

Epithelial Tissue - What Is Epithelial Tissue - Functions Of Epithelial Tissue - Epithelial Cells
In this video we look at what is epithelial tissue, some of the functions of epithelial tissue, and the different types of epithelial cells. Epithelial tissue What is epithelial tissue, where is it located, and what are its functions structure? Epithelial tissue is one of the four major types of tissue in the body and it can be found throughout many parts of the body. It lines many of the structures of the respiratory tract such as the trachea, bronchi, bronchioles and alveoli, which are the tiny air sacs in the lungs. It also lines most of the digestive tract, the epidermis of skin, the oral cavity and many of the glands of the body. Epithelial tissues have some common characteristics. It is comprised of tightly packed cells, with very little extracellular space. They also have an apical, or free surface that is exposed to an internal body space, or the external environment, and a basal, or deep surface that is attached to a thin basement membrane, which is connected to connective tissue, as you can see here. They also lack blood vessels, which is called avascular, so they get nutrients from their apical free surface or by diffusion across their basal surface from the underlying connective tissue. Epithelial tissue is also innervated, which means they have a rich supply of nerves, and epithelial cells can reproduce themselves, which is important because they go through severe wear and tear, such as in the skin, and respiratory and digestive tracts. Epithelial tissue has several important functions. It provides protection, as the skin protects the internal body from bacteria and other harmful substances. It provides sensory functions in the skin, nose, eyes and ears. Epithelial cells are important in secretions, as they secrete hormones, sweat, digestive juices and mucus. And epithelial tissue is important in absorption, such as nutrients in the gut, and the exchange of gases in the lungs. Cell structure Epithelial cells are classified based on their shape or their number of layers. Based on shape they can be squamous, which are flat, wide and a bit irregular, these are found in the air sacs in the lungs. They can be cuboidal, which are similar to a cube, about as tall as wide, and have a spherical nucleus. Columnar cells are taller than they are wide, and have an oval shaped nucleus. Pseudostratified cells, as you can see here, have varying heights, as not all of them reach the apical or top surface, but they all do connect to the basement membrane. Some epithelial cells may contain goblet cells, which secrete mucin, which forms mucus that helps with lubrication and protection, and some cells have extensions called cilia, which are sensory organs and also provide movement of mucus away from the lungs and toward the mouth. And some epithelial cells have tiny fingerlike projections called microvilli which is often termed the brush border. Microvilli helps to increase the surface area for digesting and absorbing nutrients in the intestine. Based on layers, epithelial cells are classified in three different ways, simple, stratified, and pseudostratified. Simple epithelium is only one cell layer thick, and all cells are in direct contact with the basement membrane. There is simple squamous, simple cuboidal, and simple columnar epithelium. Stratified epithelium have two or more layers of cells. Only the deepest basal layer cells have direct contact with the basement membrane and their formation looks like a brick wall. This formation provides better structural support and protection from wear or tear. Again, there are stratified squamous, stratified cuboidal, and stratified columnar epithelium. And psuedostratified epithelium is comprised of pseudostratified cells we discussed earlier. Two other notes regaurding epithelial tissue. There are also transitional epithelium, which can be in a relaxed or stretched state. In a relaxed state, they have umbrella looking rounded cells at the top apical surface, and the bottom basal cells appear cuboidal. In a stretched state, the top cells flatten and appear squamous. Some of these cells will also have two nuclei. Transitional epithelium is found in the urinary tract. There are also what is termed keratinized stratified squamous epithelium, in which the top superficial layers of cells are dead. As new cells are produced in the basal bottom region they migrate to the top, they produce a protein called keratin. These cells fill with keratin, which make them very strong, but they lose their organelles and nuclei and die. The epidermis or outer layer of the skin consists of keratinized stratified squamous epithelium. As you can see epithelial tissue and its cells have many different forms that fit its many different functions in the body.

With the Feature Line Grader you can quickly and easily set levels on any feature line by picking a start point and elevation, setting a grade and a grade direction. This tool then uses the level and grade information to automatically assign levels to each vertex of the feature line. This grading tool is a fantastic addition to the current elevation editing tools of feature lines and has some immediate applications for all sorts of grading designs such as car parks, recreation reserves, and more.
Structure of the Leaf | Plant Biology | The Fuse School
Plants make food through photosynthesis. Using their leaves, plants combine sunlight, carbon dioxide and water to make glucose and oxygen. A leaf is like a plant's food factory, collecting all of the components into one place so that photosynthesis can happen. Let's start with sunlight. The top of a leaf is exposed to the most sunlight, and so the cells specialised for trapping light are on top of the leaf. These specialised cells are called palisade mesophyll cells. They are packed full of chlorophyll - the green chemical that plants used to absorb light. Most leaves have a large surface area so that they can trap as much sunlight as possible. Moving onto carbon dioxide. This is where the bottom of the leaf comes in. There are little pores on the bottom of the leaf called stomata. The stomata open up so that carbon dioxide can diffuse into the leaf. The stomata are controlled by 'sausage shaped' guard cells, which open up to let carbon dioxide in. The guard cells can also close the stomata, to stop other things inside the leaf, like water, from escaping. The carbon dioxide comes in from the stomata, and then makes its way up through the leaf, through the gaps in the spongy mesophyll layer in the bottom part of the leaf and heads up to the palisade cells where photosynthesis occurs. Leaves are thin so that the carbon dioxide doesn't have too far to travel. The final reactant needed for photosynthesis is water. Water comes into the plant through the roots, moves up the stem and enters the leaf through the vascular bundle. The vascular bundle contains a hollow tube specifically for water movement called the xylem. The veins on a leaf are actually the vascular bundle, allowing water to be spread out through the leaf. The leaves palisade cells now have sunlight, carbon dioxide and water. They are ready to photosynthesis to make glucose and oxygen. How do leaves manage to let in the wanted things (like water and carbon dioxide) but prevent unwanted things like bacteria getting in and also prevent the reactants from escaping before being used? At the top and bottom of the leaf are epidermis cells. These produce a protective waxy cuticle layer. The waxy cuticle seals up the leaf so that the only way in and out are through the stomata, which are regulated by the guard cells. So from top to bottom, a leaf's structure: - Waxy cuticle and epidermis cells - Palisade cells (where photosynthesis occurs) - Spongy mesophyll (with vascular bundle running through for water transport) - Epidermis and cuticle, with stomata and guard cells spread throughout (allowing carbon dioxide in).

The Truth About the Titanic Has Been Revealed
Recent findings reveal the truth that has been buried for over one hundred years. Scientists have debunked the theory that the cause of the Titanic sinking was an iceberg. Why did Titanic sink? What's the real cause of the Titanic crash? HOW TITANIC SANK On April 14th, 1912 at 11:40 p.m. RMS Titanic had a terrible accident that led to its ultimate demise 3 hours later. By 2:20 a.m. in the early morning of April 15th, the biggest ship of its time had completely disappeared under the ice-cold surface of the Atlantic Ocean. The Titanic took more than 1,500 lives with it as it sank to its watery grave. TITANIC MYSTERY The cause of this horrible disaster leading to so many deaths was an iceberg the ship crashed into. Or so we’ve always been told... But scientists’ most recent findings have debunked this theory. In this video, we’ll tell you the whole truth that has been buried for over one hundred years. TIMESTAMPS How Titanic sank 0:08 How Titanic was made 1:00 The real cause of the catastrophe 3:04 The interior of the Titanic 5:10 Another tragic coincidence 6:20 Another criminal negligence: the lifeboats 7:23 Some people also blame Captain Smith 8:25 HOW TITANIC WAS MADE The Titanic had 4 massive smokestacks. Each of them weighed 60 tons, and they extended 81.5 feet above the deck. Such an impressive height was necessary to avoid covering the passengers in 100 tons of soot blown off daily. The smokestacks were placed at a 30° angle to look even more astonishing and imposing. No less awe-inspiring was the cost of the ship. Its construction demanded $7,500,000. If we take into account modern exchange rates and inflation, in 2016 they would be paying $166,000,000. Surprisingly, it would turn out cheaper than the production of the world-famous movie Titanic in 1997, which cost $200,000,000! Criminal negligence, tragic and unfortunate chain of coincidences, fire or ice: whatever it was, it took the lives of hundreds of people and still keeps the minds of scientists busy to this day.

Download yours today: https://khub.me/fr9y5 The lungs are a pair of organs in the thoracic cavity marking the terminal portion of the respiratory apparatus. Their main function is breathing, enabling the exchange of oxygen and carbon dioxide. The inhaled air reaches the lungs from the upper respiratory tract via the nasal cavity, pharynx, larynx, trachea, bronchi and the bronchioles. The right and left lungs slightly differ in their macroscopic structure: The right lung is larger in size and has three lobes, whereas the left lung only has two, due to the close proximity to the heart. Each lung has three surfaces: - Costal surface - Mediastinal surface - Diaphragmatic surface In this video tutorial we will explore the anatomy and topography of the lung and the differences between the right and left lung: - 0:16 right and left lung lobes - 0:44 horizontal and oblique fissure - 1:06 surfaces of the lung - 1:38 respiratory epithelium Want to test your knowledge on the macroscopic structure of the lungs?

NASA | The Ocean: A Driving Force for Weather and Climate
The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth's oceanic processes as one component of Earth's interrelated systems. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature. These measurements, in combination with atmospheric measurements such as surface air temperature, precipitation and clouds can help scientists understand the ocean's impact on weather and climate and what this means for life here on Earth. NASA satellites and their unique view from space are helping to unveil the vast... and largely unexplored.... OCEAN. NASA Earth Observing System Data and Information Systems (EOSDIS) EOSDIS is a distributed system of twelve data centers and science investigator processing systems. EOSDIS processes, archives, and distributes data from Earth observing satellites, field campaigns, airborne sensors, and related Earth science programs. These data enable the study of Earth from space to advance scientific understanding.

Amazing physics toys that you must see! 3
Hi Everyone :) Buy them on : https://physicstoys.blogspot.com/p/physics-toy-store.html?m=1 Follow on Instagram : https://www.instagram.com/physicsfun/ Magnetic Fluid Patterns by exploratorium: a dark ferromagnetic fluid, trapped in a small gap between two plates of glass, reacts under the influence of a powerful magnetic field in this exhibit at the Exploratorium in San Francisco. Birefringence in Calcite: the speed of light in a calcite crystal depends on polarization- the refractive index is different depending on the polarization orientation of the light transmissionitted through it. Poemotion: animation from ingenious and intricate Moiré pattern interference. Carefully align and slide the included transparent sheet of vertical lines and the amorphous images spring into sharp form and motion. A book of 31 images! Neon Flicker Flame Skull Bulb: no flame but instead emission spectra from excited neon gas due to the presence of a discharge electric current. Universe Sphere: 380000 laser etched dots, each dot representing a galaxy of stars, reveals the largest scale structure of our universe. This glass sphere contains a 3D mapping of galaxies in a volume of our universe spanning 800 million lightyears in diameter, and shows the clumping and distribution as seen by automated telescopic surveys such as that found in the Sloan Digital Sky Survey data. Hold a chunk of the universe in your hand! 360° Animated Spinning Hologram: this 3D running horse animation is a prototype of the vDisk toy which features a photopolymer type reflective hologram, which interestingly, is computer rendered and digitally produced. Unlike photographs, holograms are recordings of the interference pattern of light waves. The Levimoon: This detailed moon globe is an adjustable lamp that levitates! Charged through wireless induction via the base, the moon floats above the Earth, is illuminated from the inside to reveal the major features of the lunar surface, and will rotate when given a slight push. Europium Doped Strontium Salt: green laser target. Most phosphorescent glow-in-the-dark substances are only excited by light in the ultraviolet wavelengths, however for this substance the lower green wavelength of 532 nm excites the phosphor to glow orange. UV Fluid Flow Kaleidoscope: original glitter wand kaleidoscope made by Illusions back in the 1990s. Revolution: vintage 2D magnetic levitation- permanent magnets can only produce static equilibrium along two dimensions- here a glass mirror constrains the third dimension, and makes for a nice bearing surface for rotation. Lenz's Law: a strong neodymium magnet falls slowly down a copper bus bar as though passing through a viscous liquid. Since magnetic fields pass through copper, magneview film reveals the location of the falling dipole magnet. Moving magnetic fields from the falling magnet produce electric currents in the copper. These currents then produce magnetic fields that have the opposite polarity to the initial field. Vortices in a Kalliroscope: rheoscopic fluid reveals the intricate and beautiful turbulence induced in an enclosed fluid by rotation of the container. Wobblo: curious kinetic art toy- a hollow plastic torus contains a rolling heavy steel ball within. The motions of the center of mass of the ball and torus combine dynamically- the resulting curious motion is related to the interplay between the exchange of kinetic and potential energy and conservation of angular momentum of the system. Ferrofluid Magician: whimsical and wonderful physics toy from Taiwan. With a magnet in his hat (and a dove on his head). Reflective Wind Spinner: this one translates rotating motion into a repeating expanding (or shrinking) circle. Oil Drop Timer: immiscible fluids of different densities stay separate under gravity with the lightest density on top. Magneview Film: tracking the motion of magnets. Four disk magnets, each with a different arrangement of North and South poles, leave a different characteristic trace. Rocking Seagull Kinetic Art: counterbalanced seagull figures swing back and forth, each with a different period of oscillation in this vintage Otagiri sculpture from 1980. The Swinging Sticks: kinetic art of coupled physical pendulums. This device was featured in the movie Iron Man II (sitting on the desk of Pepper Potts). Four AA batteries and a simple kicker circuit in the base gives a push to a magnet in the end of the large rod keeping the system in motion for up to two years!

The lungs are roughly cone shaped, with an apex, base, three surfaces and three borders. The left lung is slightly smaller than the right – this is due to the presence of the heart. Each lung consists of: Apex – The blunt superior end of the lung. It projects upwards, above the level of the 1st rib and into the floor of the neck. Base – The inferior surface of the lung, which sits on the diaphragm. Lobes (two or three) – These are separated by fissures within the lung. Surfaces (three) – These correspond to the area of the thorax that they face. They are named costal, mediastinal and diaphragmatic. Borders (three) – The edges of the lungs, named the anterior, inferior and posterior borders. Lobes The right and left lungs do not have an identical lobular structure. The right lung has three lobes; superior, middle and inferior. The lobes are divided from each other by two fissures: Oblique fissure – Runs from the inferior border of the lung in a superoposterior direction, until it meets the posterior lung border. Horizontal fissure– Runs horizontally from the sternum, at the level of the 4th rib, to meet the oblique fissure. The left lung contains superior and inferior lobes, which are separated by a similar oblique fissure. Surfaces There are three lung surfaces, each corresponding to an area of the thorax. The mediastinal surface of the lung faces the lateral aspect of the middle mediastinum. The lung hilum (where structures enter and leave the lung) is located on this surface. The base of the lung is formed by the diaphragmatic surface. It rests on the dome of the diaphragm, and has a concave shape. This concavity is deeper in the right lung, due to the higher position of the right dome overlying the liver. The costal surface is smooth and convex. It faces the internal surface of the chest wall. It is related to the costal pleura, which separates it from the ribs and innermost intercostal muscles. Borders The anterior border of the lung is formed by the convergence of the mediastinal and costal surfaces. On the left lung, the anterior border is marked by a deep notch, created by the apex of the heart. It is known as the cardiac notch. The inferior border separates the base of the lung from the costal and mediastinal surfaces. The posterior border is smooth and rounded (in contrast to the anterior and inferior borders, which are sharp). It is formed by the costal and mediastinal surfaces meeting posteriorly. Root and Hilum The lung root is a collection of structures that suspends the lung from the mediastinum. Each root contains a bronchus, pulmonary artery, two pulmonary veins, bronchial vessels, pulmonary plexus of nerves and lymphatic vessels. All these structures enter or leave the lung via the hilum – a wedge shaped area on its mediastinal surface. Each bronchus enters the root of the lung, passing through the hilum. Inside the lung, they divide to form lobar bronchi – one supplying each lobe. Each lobar bronchus then further divides into several tertiary segmental bronchi. Each segmental bronchi provides air to a bronchopulmonary segment – these are the functional units of the lungs. The segmental bronchi give rise to many conducting bronchioles, which eventually lead into terminal bronchioles. Each terminal bronchiole gives off respiratory bronchioles, which feature thin walled outpocketings that extend from their lumens. These are the alveoli – the site of gaseous exchange. Vasculature The lungs are supplied with deoxygenated blood by the paired pulmonary arteries. Once the blood has received oxygenation, it leaves the lungs via four pulmonary veins (two for each lung). The bronchi, lung roots, visceral pleura and supporting lung tissues require an extra nutritive blood supply. This is delivered by the bronchial arteries, which arise from the descending aorta. The bronchial veins provide venous drainage. The right bronchial vein drains into the azygos vein, whilst the left drains into the accessory hemiazygos vein. Nerve Supply The nerves of the lungs are derived from the pulmonary plexuses. They feature sympathetic, parasympathetic and visceral afferent fibres: Parasympathetic: Derived from the vagus nerve. They stimulate secretion from the bronchial glands, contraction of the bronchial smooth muscle, and vasodilation of the pulmonary vessels. Sympathetic: Derived from the sympathetic trunks. They stimulate relaxation of the bronchial smooth muscle, and vasoconstriction of the pulmonary vessels. Visceral afferent: Conduct pain impulses to the sensory ganglion of the vagus nerve.

Here we look at: - surface area to volume ratio, how to calculate it for a simple shape, and what it really means - the small intestine and absorption of nutrients - the alveoli in the lungs - gills in fish These videos are for AQA GCSE Science - Combined Science (Trilogy) and Separate Science (Separate content is in the title or labelled in the video). The videos are planned, recorded and edited by science teacher, Kishore Vyas. website: TheScienceBreak.com The Science Break on: instagram: http://www.instagram.com/thesciencebreak snapchat: https://www.snapchat.com/add/thesciencebreak twitter: https://twitter.com/TheScienceBreak

Structure of Bacteria | Biology for All | FuseSchool
At about 3.5 billion years old, bacteria are one of the oldest living organisms on earth. They are responsible for a range of diseases including cholera, tuberculosis and the plague amongst many others. But they aren’t all bad; there are trillions of good bacteria living in your gut that are essential to your health. They can produce vitamins, prevent tumour formation, help the immune system fight pathogens and protect against carcinogens, amongst other benefits. Bacteria cells are very small; much smaller than plant and animal cells. They are found practically everywhere on Earth and live in some of the most unusual and seemingly inhospitable places. Bacteria are unicellular prokaryotes. They come in lots of different shapes and sizes, but contain the same elements. As they are prokaryotes, they do not have a membrane bound nucleus. The DNA is in the cytoplasm, in the area known as the nucleoid. Bacteria have a flexible cell wall that protects them from physical damage and is exposed to the external surroundings. A flagellum that helps the bacteria to move. Bacteria have two types of DNA; plasmid DNA and chromosomal DNA. The chromosomal DNA carries most of the genetic information. The plasmid DNA forms small loops and carries extra information such as resistance to antibiotics, production of toxins and tolerance to toxic environments. The ribosome is involved in protein synthesis. The pili enable the bacteria to attach to hosts and surfaces like teeth, intestines and rocks. They are also involved in DNA exchange between bacteria, in bacterial conjugation. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.
