This video elaborates the process of Photosynthesis, by which plants make their own food. Photosynthesis is the process used by the plants to make their food. In simpler terms, conversion of light energy into chemical energy by plants is called photosynthesis. This chemical energy is used by the plants for growth and nourishment. Photo means light and synthesis means putting together. Humans need some essential things like fire, water, vegetables etc to cook food. Similarly, to make their own food, plants also need some essential factors like Light, water, nutrients, soil etc Plants get light from the sun, water from the ground and carbon dioxide from air. All these factors including air, water, carbondioxide and sunlight together help plants churn out their own food. Plants have tubes called Xylem located in the stem through which the water from the ground is sucked into the leaves. This system works similar to the humans sucking in liquids through a straw. The Xylem is spread throughout the different parts of plant including stem, branches, all the way upto their leaves, and transports vital nutrients to the entire plant. Xylems in plants are like blood vessels in the human body that act as an important means of transport for water and nutrients. Leaves on the plants have pores, very similar to pores on the skin of our body. These pores are called stomata. These stomata are responsible for the exchange of gases. The carbon dioxide present in the air, which is responsible for photosynthesis, enters the plant through these stomata. Oxygen also comes out from the same stomata. Leaf has important cells called Mesophyll cells. These cells contain a green color component called chloroplast. This chloroplast is responsible for the green color of plants and leaves. Once the carbon dioxide and water reach the chloroplasts, in the presence of sunlight, the process of photosynthesis starts to take place. The following reaction takes places in the leaves of the plant during photosynthesis: Carbon dioxide + water + [in the presence of light energy] Oxygen + glucose (or Carbohydrates) The products formed are glucose and oxygen. Carbohydrates, which are a form of glucose, are synthesized from carbon dioxide and water. Glucose is used by the plants for the growth. Some of the glucose is used immediately and the extra glucose which is not used is stored in the form of starch, in the leaves. Some amount of glucose is also stored in the roots of the plants. The extra glucose is used to perform photosynthesis when there is no sunlight. Oxygen is given out into the air through the stomata in the process of photosynthesis. The oxygen that is released is used by human beings to breathe in during their respiration process. Ever wondered why this process is called photosynthesis? The word photosynthesis is a combination of two words: Photo and Synthesis. Photo means light in Greek and Synthesis means putting together or combining. Hence, photosynthesis literally means combining water and carbon dioxide in the presence of light. So, the essential factors for photosynthesis to take place include: Sunlight Water Carbon dioxide Underwater photosynthesis takes place at a slower pace than the normal photosynthesis. This is because energy from the sun is absorbed by the water layers and only some amount of the energy reaches the plant. There are some plants which don't need the process of photosynthesis to grow. Such plants include Mushroom, Venus flytrap etc. Mushroom gets the food from the ground and its surrounding areas. Venus flytrap traps and catches small insects which come near the leaves and eat them.
Photosynthesis & Respiration
Photosynthesis Light interception by leaves powers photosynthesis All organisms, animals and plants, must obtain energy to maintain basic biological functions for survival and reproduction. Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2). The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development. There are several structures within a leaf that have important roles in the movement of nutrients and water throughout a plant. Each plant contains a branched system of tubes called xylem, which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis). Water flows up from the roots, through the trunk and branches, to the leaves, where it is used in photosynthesis. Alongside xylem is another system of tubes called phloem, which transports the glucose formed in photosynthesis into the branches, fruit, trunk and roots of the tree. T

All About Plants : Usda Ars
Plants can be found all over the Earth. You can find them at the top of mountains and in the oceans. They grow in the cold polar regions, in the hot dry deserts and everywhere in between. All life on Earth depends on plants. If there were no plants, there would be no life. Plants provide us with food, clothing, shelter, medicine, and energy. They produce gases for our atmosphere and help to keep it clean. I guess you could say that plants are important. In order for plants to grow and be healthy they need six things. They need light, nutrients, water, the right temperature, space to grow and gases in the air. Plants get all of these things from their environment. Plants that come from seeds have four main structures that help them get what they need from their environment. From the bottom up, they have roots, stems, leaves, and flowers. Two of the things a plant needs, water and nutrients, are retrieved from the soil through the root system. Nitrogen and minerals such as calcium, sulfur, potassium, magnesium, and phosphorus dissolve in water and are absorbed by the roots of a plant through root hairs. Most plants have billions of root hairs which are tiny structures near the end o
From Glow in the Dark Rabbit to Anti-Cancer Purple Tomatoes here are 18 Genetically Modified Organisms You Don't Know About Subscribe to Talltanic http://goo.gl/wgfvrr # 9 Fish Strawberries The ripest and juiciest strawberries you got from the supermarket might contain the genetic traces of a fish. Scientists have been experimenting with combining strawberries with the anti-freeze genes that are found in cold water fish like Arctic Char and Sea flounders which help the strawberries resist freezing and dying in bad weather. Luckily, it doesnt create a weird fishy-tasting strawberry. # 8 Glow in the Dark Rabbit Most genetically modified organisms have a scientific purpose in mind or a greater goal that usually justifies messing with somethings DNA spread. However, Eduard Kac used genetic engineering for creating works of art rather than for scientific research. His most notorious work was the Glow in the Dark rabbit named Alba. It sparked a debate about animal rights, but Alba died before anything was resolved. # 7 Goats Spliced with Spiders When you think of genetically splicing something with a spider, you usually think of superheroes with spider themed super powers. However, in real life, you can find animals that have been genetically combined with spiders - goats. Spider silk is flexible and strong, and some even want to try and produce it on a larger scale so we can use it to make things like parachute cords. One lab has spliced spiders genes with a goat so that these flexible and strong spider silk genes would be replicated in their milk. This silk milk is also able to create Biosteel, a strong web-like material. # 6 Golden Rice Rice is a major staple food in many parts of the world partly because it's cheap and partly because it helps you feel full even when you dont have much to eat. However, the normal white rice isnt very healthy for you. That is why scientists are working on Golden Rice, rice that was spliced with vegetables like squash and carrots that not only create the golden color but include beta-carotene which is more nutrient dense and could help prevent blindness in children who eat it. # 5 Ear Mouse The most notorious genetically modified animal might be the ear mouse or the Vacanti Mouse which was created in 1995 by scientists in Massachusetts. The scientists wanted to prove that cartilage structures could be grown on other living creatures before being removed and transplanted into humans who need it. However, this mouse would quickly become famous or infamous as it went onto the Jay Leno show and then used as a mascot by animal-rights groups who were opposed to genetic modifications. # 4 Scorpion Cabbage The Androctonus australis is one of the most dangerous scorpions in the world with a venom that can cause tissue damage and death. So of course, we combined the genes from this scorpion with cabbage intended for human consumption. The gene of the scorpions venom changed when it was spliced with the cabbage. The venom is now only poison to insects, which spasm and die when they try to eat the crop. That same poison is supposedly completely harmless to humans, making it the perfect crop. # 3 Anti-Cancer Purple Tomatoes Researchers have created a tomato that is not only more flavorful but would also help prevent cancer. The researchers spliced tomatoes with the snapdragon flower to create a deep, purple tomato that almost looks like a blackberry. These super tomatoes contain potent antioxidants and inhibit the growth of cancer cells, ease the symptoms of diabetes, and even relieve the pains of growing old. You might just see purple tomatoes on your pizza someday soon. # 2 Chinese Dog-Pig This image went around the internet with a bunch of people thinking it was some sort of failed chimera of a pig and a dog because of its pink skin and strange tufts of hair. While it was not an animal that was genetically engineered in a lab, it is an animal that has been genetically engineered over generations and generations, like most dogs are. This dog, in particular, is the Hairless Chinese Crested Dog - an expensive and rare breed of dog that is highly sought after by some people. Even though the winner of the annual worlds ugliest dog contest is usually a Chinese Crested. # 1 Less-Flatulent Cows You might have heard that cows produce an excess of methane, which contributes to the dangerous greenhouse effect. Its hard to make cows stop producing methane since theyre some of the most populous domestic livestock in the world and that is a natural part of their digestive progress. Until we genetically modified cattle to produce 25 less percent of the bacterium in their digestive tract that creates methane gas. Basically, we made cows that fart less.
Storage Forms Of Glucose In Organisms
When carbohydrates from the foods you consume are digested, glucose is the smallest molecule into which a carbohydrate is broken down. Glucose molecules are absorbed from intestinal cells into the bloodstream. The bloodstream then carries the glucose molecules throughout the body. Glucose enters each cell of the body and is used by the cell’s mitochondrion as fuel. Carbohydrates are in nearly every food, not just bread and pasta, which are known for “carbo loading.” Fruits, vegetables, and meats also contain carbohydrates. Any food that contains sugar has carbohydrates. And, most foods are converted to sugars when they are digested. Once an organism has taken in food, the food is digested, and needed nutrients are sent through the bloodstream. When the organism has used all the nutrients it needs to maintain proper functioning, the remaining nutrients are excreted or stored. You store it: Glycogen Animals (including humans) store some glucose in the cells so that it is available for quick shots of energy. Excess glucose is stored in the liver as the large compound called glycogen. Glycogen is a polysaccharide of glucose, but its structure allows it to pack compactly, so more

Dear Mark, I’m trying to understand how glucose that’s created by proteins and fats is used and stored. Is that ~200g of glycogen stored in the muscles to be used for exercise, or is it stored in the liver and used to fuel the brain and “day-to-day” functions? Also, if muscle glycogen is depleted, will ingested carbohydrates be used first to replenish muscle glycogen and then to fuel other daily functions, or are they used the other way a ...
In 1922, Canadian scientists isolated insulin for the first time. Now, over 80 years later, our neighbors to the north are helping diabetics again by devising the cheapest way yet to produce insulin. This advance could significantly reduce the expense of treating the disease, which currently costs the US $132 billion dollars a year. To create the cheap "prairie insulin," scientists at the University of Calgary genetically engineered the human gen ...
Metabolism is the term used to describe the many chemical reactions that are involved in the utilisation of nutrients in the body. If these reactions are investigated more closely, it will be found that they may be placed into one of two categories known as anabolism (building more complex compounds from the simple ones resulting from digestion) and metabolism (breaking down of these complex compounds to produce energy for normal body functions). ...
