Chlorophyll A and Chlorophyll B are two types of chlorophyll. Chlorophyll is the substance that is present in the leaves of plants and is responsible for their green color as seen by us.Chlorophyll absorbs sunlight and makes use of this energy to synthesize carbohydrates from water and carbon dioxide.he major difference between A and B is the molecule CH3 in the side chain in A, while it is CHO in B. Energy absorption at wavelengths at which A is ineffective is done by B and vice versa. Related posts: 1  Difference Between Fermentation and Respiration.
Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum.Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.There are various types of chlorophyll structures, but plants contain chlorophyll a and b. These two types of chlorophyll differ only slightly, in the composition of a single side chain.reen light is not absorbed but reflected, making the plant appear green.
