What is the main purpose of photosynthesis?
Photosynthesis is the process by which plants use light energy to create food. Carbon dioxide and water combine to form glucose and oxygen. The process of photosynthesis occurs in the chloroplasts of plant cells.
Photosynthesis: How Plants Make Food
Chloroplasts: Organelles that contain pigments and are responsible for photosynthesis. Glucose: A sugar molecule that is produced by photosynthesis. Light Energy: Energy from the sun that is used by plants to power photosynthesis.
Concepts:
What is the most interesting thing about photosynthesis?
- The way plants produce oxygen.
- The way plants capture energy from the sun.
- The ability of plants to grow in different environments.
- The role of photosynthesis in the food chain.
Photosynthesis produces more oxygen than all other sources combined! Different plants have adapted to absorb different parts of the visible spectrum. Some plants can store energy from the sun for up to two weeks!
