The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.
