Plastids | Cell-Structure & Function | Biology | Class 9

Chloroplasts – They contain chlorophyll and are involved in photosynthesis, where light energy is converted to chemical energy. Chloroplasts contain compartments called stroma and grana. Grana contains structures called thylakoids that contain chlorophyll. The stroma contains enzymes needed for carbohydrate and protein synthesis.
Chromoplasts – These give plants yellow, red, or orange colors because they contain pigments like carotene.
Leucoplasts – These are colorless plastids that store either carbohydrates (Amyloplasts), oils, and fats (Elaioplasts) or proteins (Aleuroplasts).
Let us learn more about them, in this video.
