What is the function of chloroplasts in plant cells?

Chloroplasts are organelles in plant cells responsible for photosynthesis, the process by which plants convert sunlight, carbon dioxide, and water into glucose (a form of sugar) and oxygen. Chloroplasts contain the pigment chlorophyll, which absorbs light energy. This energy is used to power the conversion of carbon dioxide and water into glucose, which plants use as food. Chloroplasts enable plants to produce their own energy, making them primary producers in ecosystems and playing a critical role in the Earth’s carbon cycle.
