Chloroplasts belong to a family of plant organelles called plastids, which includes several nonphotosynthetic variants such as etioplasts in darkgrown seedlings and carotenoidrich chromoplasts in fruits. A specific feature of the plastid family is the ability to interconvert in response to developmental and environmental cuesfor example, during deetiolation or fruit ripening. The chloroplast, the home of photosynthesis, is the most representative and characteristic organelle in plants and is enclosed by the outer envelope and inner envelope membranes.
