Q

Give five ways in which plants use the glucose they have made

A
  1. Celluar respiration - releases energy
  2. Cellulose (complex carbohydrate) - strengthen cell walls
  3. Starch - long term storage, compact, insoluble
  4. Amino acids = proteins ( glucose + nitrate ions)
  5. Oils + fats - stored as future energy source
