what are the two main functions of chloroplasts

The two main functions of chloroplasts are photosynthesis and carbon fixation. Chloroplasts are organelles in plant cells that capture sunlight using chlorophyll and convert it into chemical energy through photosynthesis, producing glucose and oxygen. They also perform carbon fixation, which is the process of converting carbon dioxide from the atmosphere into organic molecules essential for plant growth and energy storage. These functions make chloroplasts vital for sustaining plant life and providing oxygen to the atmosphere.
