Plant cell
They have plastids. The most notable are the chloroplasts, which contain chlorophyll. This green-colored pigment absorbs sunlight, and allows the plant to make its own food by photosynthesis. Other types of plastids are the amyloplasts, which store starch, elaioplasts for fat storage, and chromoplasts for making and storing pigments. Like mitochondria, plastids have their own genomes of about 100–120 unique genes. It is thought they started as prokaryotic endosymbionts living in the cells of an early eukaryotic ancestor of the land plants and algae.
