7
Q
Give five ways in which plants use the glucose they have made
A
- Celluar respiration - releases energy
- Cellulose (complex carbohydrate) - strengthen cell walls
- Starch - long term storage, compact, insoluble
- Amino acids = proteins ( glucose + nitrate ions)
- Oils + fats - stored as future energy source
