- Chloroplasts have a double membrane structure and an inner membrane system called thylakoids, where the light-dependent reactions occur.
- In addition to chlorophyll, chloroplasts house other pigments that aid in capturing different wavelengths of light during photosynthesis.
- Chloroplasts play a crucial role in maintaining the balance of oxygen and carbon dioxide in the atmosphere.
