Structure of the Leaf | Plant Biology | The Fuse School
 
03:43
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).

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

Plant "Breathing" Mechanism Discovered
 
02:21
A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. A study by scientists at the Department of Global Ecology has now overturned the conventional belief about how these important structures called stomata regulate water vapor loss from the leaf--a process called transpiration. They found that radiation is the driving force of physical processes deep within the leaf.

Travel of Air Through Respiratory System - Gas Exchange in the Lungs - Nose to Alveoli Pathway
 
02:10
Gas Exchange - Delivery of Oxygen & Elimination of Carbon dioxide - Medical Animation Air first enters the body through the mouth or nose, quickly moves to the pharynx (throat), passes through the larynx (voice box), enters the trachea, which branches into a left and right bronchus within the lungs and further divides into smaller and smaller branches called bronchioles. The smallest bronchioles end in tiny air sacs, called alveoli, which inflate during inhalation, and deflate during exhalation. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation.

Respiration - Why is it not good to sleep under a tree at night? | #aumsum
 
02:19
Topic: Respiration Why is it not good to sleep under a tree at night? Hey. You look so tired. Why don't you take rest here? No. Please don't sleep under that tree. It is quite harmful. See, you are not able to breathe properly, right? Do you know why? Wait, I will tell you. This is because during the day, in the presence of sunlight, plants take in carbon dioxide and release oxygen in the process of photosynthesis. However, they even respire simultaneously. In this process, plants take in oxygen and release carbon dioxide. But the production of oxygen is more than the production of carbon dioxide. Hence, if we sleep under a tree during daytime, we may get a good amount of oxygen, thus giving us a nice sleep. However, at night, plants do not perform photosynthesis due to the absence of sunlight. But respiration still goes on. Hence, as compared to oxygen, the proportion of carbon dioxide around the trees is more. Thus, if we sleep under a tree at night, we may feel suffocated due to lack of oxygen. Moreover, inhalation of excess carbon dioxide is harmful to human beings. Therefore, it is not good to sleep under a tree at night.

Funded by MeitY (Ministry of Electronics & Information Technology) Study of Stomatal Distribution on Leaves :- Stomata are minute pores found on the epidermis of leaves and young shoots of plants that are used to control exchange of gases. The pore is surrounded by a pair of specialised cells called the guard cells that are responsible in regulating the size of the opening. Distribution of stomata varies between monocots and dicots, between plant species, and between the underside and top side of the leaves on a plant. Stomata are found more on plant surfaces thriving under higher light, lower atmospheric carbon dioxide concentrations and in moist environments. Usually the lower surface of a dicot leaf has a greater number of stomata while in a monocot leaf they are more or less equal on both surfaces. In most of the floating plants, stomata are found only on the upper epidermis. This video explains how to study the stomatal distribution on the upper and lower leaf surfaces and to calculate the stomatal index.

Steroids control gas exchange in plants
 
03:05
Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the atmosphere passes through stomata each year, as well a water volume twice that of the whole atmosphere. As the key conduits for CO2 uptake and water evaporation, stomata are critical for both our climate and plant productivity. Thus, not surprisingly, the total number and distribution of stomata are strictly regulated by plants to optimize photosynthesis while minimizing water loss. The mechanisms for such regulation have remained elusive.

How to prepare stomata slide for microscopic study of stomata-  हिंदी में
 
04:01
On the outer layer of the leaf of a plant are microscopic holes called stomata. Stomata control gas exchange and water loss by opening and closing. Stomata are of particular interest to plant breeders because plants with smaller or fewer stomata tend to have lower levels of evaporation and can survive drought better than those plants with more stomata. Additionally, researchers often study stomata for the effects of carbon dioxide and changes in atmospheric composition. In short, stomata are studied to measure any type of plant response to stress. Normally stomata open in the morning and close during the night. However, not all plants open their stomata during the day. Some plants such as cacti and succulent plants open their stomata at night and close them during the day, in order to prevent losing too much water. Stomata are usually found on both the top and the bottom of a leaf. Many plants have more stomata on the underside of the leaf. However there are exceptions, monocots, like grasses, have similar numbers on both the top and the bottom. Plants whose leaves rest on the surface of the water, like water lilies, often have very few stomata on the wet underside of their leaves. There are basically 02 common methods for stomata view- 1- By peeling the upper layer of a leaf as we have shown in the video 2- If it is not possible then place a clear nail polish in it and after drying place a transparent tape over it and peel it and transfer it under a microscope to see the stomata. Apparatus and Materials Required: Sampl leaves, forceps, needles, watch glasses, glass slides, a dropper, coverslips, a brush, blotting paper, safranin, glycerine and a compound microscope. Procedure: 1. Remove a healthy leaf from the potted plant. 2. Remove a part of the peel from the lower surface of the leaf. You can do this by folding the leaf over and gently pulling the peel apart using forceps. Keeps the peel in a watch glass containing water. 3. Put a few drops of safranin stain in a watch glass. 4. After 2-3 minutes take out the peel and place it on a clean glass slide. 5. Put a drop of glycerin over the peel and place a clean coverslip gently over it with the help of a needle. 6. Remove the excess stain and glycerin with the help of blotting paper. 7. Observe the slide under the low-power and high-power magnifications of the compound microscope.

The compound used, or oxidized, during respiration is called a respiratory substrate. Carbohydrates, fats, and proteins are examples of respiratory substrates, and carbohydrates are the preferred respiratory substrate among them. Respiration produces a great deal of energy that is needed by plants to grow and stay healthy. Excess sugars produced by photosynthesis that are not needed for respiration and growth are stored as starch which can then be converted back to sugars when needed during periods of low light. The rate of respiration can be measured in terms of gas exchange, that is, consumption of the respiratory substrate oxygen, or evolution of carbon dioxide. This video explains how to study the rate of respiration in germinating seeds having different substances such as wheat (carbohydrates), mustard (fats) and bean (proteins).
