Photosynthesis
DEFINITION:Photosynthesis is the process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. it has two phases as below.
==> A The Light-Dependent Reaction Photosynthesis relies on flows of energy and light energy. Light contains many colours. Certain red and blue wavelengths of light are the most effective in photosynthesis. None of the photosynthetic pigments absorb green light; as a result, green wavelengths are reflected, which is why plants appear green. ==> B The Light-Independent Reaction Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are supreme sugar factories, which produce glucose. Plants use much of this glucose, a carbohydrate, as an energy source to build leaves, flowers, fruits, and seeds. They also convert glucose to cellulose, cellulose the structural material used in their cell walls. Most plants produce more glucose than they use, and they store it in the form of starch and other carbohydrates in roots, stems, and leaves. The plants can then draw on these reserves for extra energy or building materials.
