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.
