Chromoplasts are colored plastids found in roots, leaves, flowers and ripe fruits. They contain lipid-soluble pigments, referred to as carotenoids, that provide color to many different types of plants and flowers.
Unlike the more familiar chloroplasts, which give plants their green color, chromoplasts produce red, yellow and orange colors. At the cellular level, they are similar in size to chloroplasts but are vastly different in shape. Chromoplasts give color to carrots, ripe tomatoes, red peppers, squash, pumpkins and various other red, yellow and orange fruits, vegetables and flowers.
Plastids produce and store pigment in the cells of plants and algae. They consist of chromoplasts, chloroplasts and leucoplasts.
