photosynthesis is the process in which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
chlorophyll is the pigment or the green color of plants, leaves, and algae. it absorbs blue and red light rays which turns it green. and it also reflects green light rays which gives plants there color.
during photosynthesis the plants capture the suns light energy. plants use that energy to turn water and carbon dioxide into a sugar called glucose. the glucose makes energy and makes other substances like cellulose and starch.
