Process of Photosynthesis :: essays research papers

Process of PhotosynthesisPhotosynthesis is act by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the pedigree in the presence of light. Green plants and certain other organisms use the cogency of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the fundamental muscle source for just about all organisms. An extremely important byproduct of photosynthesis is type O, on which most organisms depend. Photosynthesis has far-reaching implications. Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Moreover, the oxygen humans and other animals breathe is the oxygen rel succourd during photosynthesis. Humans are alike dependent on ancient products of photosynthesis, know as fossil fuels, for preparation most of our modern industrial energy. These fossil fuels, inclu ding natural gas, coal, and petroleum, are self-possessed of a complex mix of hydrocarbons, the remains of organisms that relied on photosynthesis millions of years ago. Thus, virtually all life on earth, directly or indirectly, depends on photosynthesis as a source of food, energy, and oxygen, making it one of the most important biochemical processes known. Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. single plant leaf is composed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts. The chloroplast, an oval-shaped structure, is divided by membranes into numerous disk-shaped compartments. These dislike compartments, called thylakoids, are arranged vertically in the chloroplast like a mint candy of plates or pancakes. A stack of thylakoids is called a granum, the grana lie suspended in a fluid known as stroma. Photosynthesis is a very complex process, and for the sake of convenience and ease o f understanding, plant biologists divide it into two stages. In the first stage, the light-dependent reaction, the chloroplast traps light energy and converts it into chemical energy contained in nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), two molecules apply in the second stage of
