Biology A-level: PhotosynthesisThis shows that carbon dioxide and water are turned into glucose and oxygen in a plant, using light as energy.The carbon dioxide enters the plant by stomata (in the leaves) or lenticels (in the stem). The water enters through the roots and moves up through the plant in xylem vessels. Light is required as an energy source for the reaction and chlorophyll is necessary to absorb the light.The glucose made may be used to make other substances or it may be used in respiration. The oxygen may diffuse out through the stomata or it may be used in respiration.Light energy is necessary but it must be harvested and trapped by the photosynthetic pigments to be of any use.Chlorophyll absorbs light from the visible part of the electromagnetic part of the spectrum, but there are several types of chlorophyll...chlorophyll achlorophyll bchlorophyll cbacteriochlorophyll (found in photosynthetic bacteria!)There are also other families of pigments, such as the carotenoids.Not all wavelengths of light are equally absorbed and different chlorophylls absorb more strongly in different parts of the visible spectrum.Absorption and Action SpectrumsThe action sp
