Respiration

During photosynthesis, plants produce glucose from carbon dioxide and water using light energy.

Carbon dioxide + water —→ light ( chlorophyll ) ——- glucose + oxygen

Uses:

1. Starch- insoluble, storage form of carbohydrate

2. Cellulose- used to build cell walls, adds strength to cell walls

3. Lipids- used for storage in seeds

4. Amino acids- nitrates absorbed from soil form amino acids

5. Proteins- amino acids join together to form specific proteins.
