There are several different types of chlorophyll including chlorophyll a, chlorophyll b, chlorophyll c, chlorophyll d, chlorophyll e and bacterio-chlorophyll. The various types of chlorophyll are found in different organisms and are all involved in photosynthesis.
Chlorophyll is an important pigment in the process of photosynthesis and is found in all photosynthetic organisms including plants, blue-green algae and eukaryotic algae. It is a photoreceptor that is found in the chloroplasts of green plants. Chlorophyll a and chlorophyll b are the two major types of chlorophyll and differ only in the composition of one of their structural sidechains. Chlorophyll a is the most prevalent type of chlorophyll. It is found in plants, algae and other aquatic organisms. This type of chlorophyll absorbs red, blue and violet wavelengths. It gets its color by reflecting green, thus giving plants their green color. Chlorophyll b is found primarily in plants as well, but this type absorbs blue light only and is yellow in pigment. Chlorophyll c and chlorophyll d are less common and are found in different algae. Chlorophyll e is a very rare type of chlorophyll that is found in some golden algae, and, as the name suggests, bacterio-chlorophyll is found in certain bacteria.
