👉 In biology, a chromoplast is a type of plastid in plant cells. It contains the DNA and other genetic material required for the development of chloroplasts, which are organelles found in plants, algae, and some bacteria. The chromoplasts play an important role in photosynthesis, as they contain the pigments chlorophyll, which is responsible for capturing light energy from sunlight to produce oxygen and carbon dioxide. The presence of these structures allows plants to convert sunlight into chemical energy
