Chloroplast Facts

Chloroplasts are the specialised intracellular organelle that performs photosynthesis in the daytime. The light-absorbing pigments called chlorophyll are present in the thylakoid membrane of the chloroplast. Chlorophyll pigments are responsible for imparting green colours to the plant, algae, and other autotrophic microorganisms. This green colour is achieved by the absorption of blue and red light energy and the transmission of green light waves.
