Chloroplasts are the part of plant and algal cells that carry out photosynthesis, the process of converting light energy to energy stored in the form of sugar and other organic molecules that the plant or alga uses as food. They may be cup shaped (Chlamydomanas), girdle shaped (Ulothrix), spiral (Spirogyra), but normally discoid in most of the other groups like in Chara.
