Photosynthetic Nutrition For Health and Life
Living organisms are constantly undergoing chemical reactions which give rise to energetic changes in their bodies. All these reactions and changes are called energy production. Basically, production consists of two processes, the production or production of complex substances from simple materials and energy, and the decomposition or breakdown of these complex and energy substances. The first process is known as anabolism and the second as catabolism.
One of the main characteristics of organisms is the ability to eat. This is referred to as food. Food is therefore, the process of obtaining energy and materials for cell production, including the maintenance and repair of cells and growth. In living organisms, nutrition is a complex series of anabolic and catabolic processes through which nutrients taken into the body are converted into complex substances (mainly for growth) and energy (for work). In animals, nutrients are often in the form of complex, insoluble compounds. These are broken down into simpler compounds, which can be absorbed into the cells. In plants, complex nutrients are first synthesized by plant cells and then distributed to all parts of the plant body. Here, they are converted into simple, soluble forms, which can be absorbed into the protoplasm of each cell. The essential raw materials for the production of these complex food items are obtained from the air and soil in the plant environment.
All living organisms that cannot produce their own energy supply through either photosynthesis or chemosynthesis are known as hetero strophes or hetero strophic organisms. Hetero strophic means feeding on others’. All animals have hetero strophes. Other organisms such as many types of bacteria, some flowering plants and all fungi use this food method. The way hetero strophes get their food is very different. However the way food is processed into usable form within the body is similar in most of them. But all green plants have the ability to produce carbohydrates from certain raw materials obtained from the air and soil. This energy is important not only to plants themselves but also to animals, including humans, which depend directly or indirectly on plants for food.
Photosynthesis is the process by which plants produce their food by using energy from sunlight and available raw materials. It is the synthesis of carbohydrates in plants. It occurs in the chlorophylls (ie green) cells of leaves and fruits only. These green cells contain chloroplasts, which are important for food production. All the raw materials needed for photosynthesis, namely, water and mineral salts from the soil, and carbon dioxide from the atmosphere have, therefore, to be transported to the cells of chlorophylls, which are the most in the leaves.
The small pores, or stomata, which occur in greater numbers on the lower surfaces of many leaves, allow gases from the atmosphere to pass into the veins. The stoma is made up of oval-shaped epidermal cells known as guard cells. Each stoma is the opening of a sub-stomatal air chamber. This is a large intercellular air space, which is located close to the stoma. It is continuous with other intercellular air spaces found in the leaf. The size of each stomata pore depends on the curvature of the guard cells flanking it. When the guard cells are filled with water they become swollen, or turgid, and so the pore opens. However, when the water level drops they become soft, or flaccid, and collapse, as a result, which the pores close. When the stoma is open air enters the sub-stomata chamber and diffuses throughout the intercellular air dissolves in water, which surrounds the cells. This carbon dioxide solution then diffuses into the cells of the leaf, especially the palisade cells. Here, it is used by chloroplasts for photosynthesis.
Water carrying dissolved mineral salts such as phosphates, chlorides and bicarbonate of sodium, potassium, iron calcium and magnesium, is absorbed from the soil by the roots. This soil water enters the root hairs through a process called osmosis the movement of water molecules from an area of low concentration to an area of higher concentration through a semi-permeable membrane. It then travels upwards from the roots, through the stem to the leaves through the xylem tissue. It is transported to all cells, through veins and their branches.
Chloroplasts contain the green pigment, (chlorophyll) that gives plants their color and is capable of absorbing light energy from the sun. This energy is used for one of the first important steps in photosynthesis; namely, the splitting of water molecules into oxygen and hydrogen. This oxygen is released into the atmosphere. We use hydrogen components even reduce carbon dioxide, in a series of enzymes and energy-consuming reactions, to form complex organic compounds such as sugars and stars.
During photosynthesis, high-energy compounds such as carbohydrates are produced from low-energy compounds such as carbon dioxide and water in the presence of sunlight and chlorophyll. As solar energy is essential for photosynthesis, the process cannot take place at night due to the absence of sunlight. The final products of photosynthesis are carbohydrates and oxygen. The former are divided into all parts of the plant. The latter is given off as a gas through the stomata back to the atmosphere in exchange for carbon dioxide that has been taken in. the phenomenon of photosynthesis in green leaves can be demonstrated by experiments showing the absorption of carbon dioxide, water and energy by the leaves, and the production of oxygen and carbohydrates. Simple experiments can be set up to show the supply of oxygen by green plants, the formation of carbohydrates (namely, starch) in leaves and the requirements of carbon dioxide, sunlight and chlorophyll for the formation of starch in green leaves.
Experiments in biology by placing biological objects such as plants and animals or parts of plants and animals under unusual conditions, for example pots, cages or boxes. If you set up some experiments to show the effects produced by the absence of carbon dioxide during the photosynthetic process, then the result obtained from such an experiment can be argued as partly due to the transfer of biological material under natural test conditions. , therefore, necessary to set up two almost experimental symbols; one is under normal conditions (control experiment) where all factors necessary for photosynthesis are present while the other (experimental experiment) is under a condition where one factor is removed or varied while all other factors are present. This allows the researcher to make sure that the result shown by his test is due to an exception or different ratio and not to the test schedule. Therefore, the controlled trial serves as a guide to ensure that the conclusion obtained through the trial test is not an illusion.
After some good experiments the observation clearly shows that oxygen is released only when photosynthesis takes place, i.e. during the day. No starch can be formed in the absence of sunlight even though all other essential substances such as water, carbon dioxide and chlorophyll can be present.
Photosynthesis is a basic nutrient part of healthy life and it plays an important role in living organisms. The complex cellular structures of plants are made from the primary product of photosynthesis, namely, a simple carbohydrate such as glucose. At this stage, you must realize that, although we have put a lot of emphasis on photosynthesis, the process of protein synthesis is just as important as before. During protein synthesis, nitrogenous compounds obtained by plants and in some cases, phosphorus and other elements, combine with glucose to form various plant proteins.
Besides contributing to the production of plant proteins, glucose is also important because it can be converted into fats and oils after a series of chemical reactions. It is also the primary product from which other organic compounds are formed.
The importance of photosynthesis in all food cycles cannot be overstated. Animals are unable to use the sun’s energy to synthesize energy compounds from easily-available substances such as water and carbon dioxide found in the atmosphere around us, instead of ultraviolet rays from the sun causing some to the living body; melanin and keratin it affects the color and strength of the animal’s skin, and some internal damage. From bones, therefore, it is fortunate that plants have the ability to use the energy provided by sunlight to accumulate and preserve the energy-rich compounds on which are all the characteristics of animal life that reliable.
For his survival, man eats not only plant products like fruits, vegetables and grains, but also animals like meat and fish. Mammals and other herbivorous animals depend on plant life for their existence. While some fish are herbivorous, others have a mixed diet and a large number are completely carnivorous. Microbial animals depend directly on plants for life. Their immediate food consists of smaller animals which themselves must feed, if not completely, then partially, on plants. Photosynthesis is the first step in all food cycles.
During the process of photosynthesis, carbon dioxide is removed from the air and oxygen is added to it. If this purification process were not present in nature, the atmosphere would soon be filled with carbon dioxide given off during the respiration of animals and plants and during the decomposition of organic matter so that all life would gradually cease. Without photosynthesis, there is no food. And if there is no food, there will be no living thing. And if there is no living creature on earth it will still be formless and empty. It is not possible for living things to work if photosynthesis does not take place. I wonder what will be the fate of living things today or in the future, when photosynthesis stops.
