Photosynthesis is a process used by organisms that contain chlorophyll. They turn light energy into chemical energy. They make glucose from carbon dioxide and water. Oxygen is released as a by-product. The light-dependent reactions happen in the thylakoid membranes. The Calvin cycle happens in the stroma.
Terms explained:
- Chlorophyll: The green substance that absorbs light.
- Glucose: A type of sugar used for energy.
- By-product: Something made during a process but not the main product.
- Light-dependent reactions: The part of photosynthesis that uses light directly.
- Thylakoid membranes: Structures inside plant cells where light-dependent reactions happen.
- Calvin cycle: The part of photosynthesis that uses carbon dioxide to help make glucose.
- Stroma: The fluid-filled space around the thylakoid membranes.
