insoluble
another energy store
provide energy for photosynthesis at night
can be stored in tubers and bulbs

Question 8

why do plants need cellulose?

used in cell walls

strengthen to keep the plant upright

Question 9

why do plants need amino acids and proteins?

Answer 9

glucose and nitrate ions make amino acids
amino acids = proteins
growth and repair

why do plants need fats and oils?

Answer 10

energy storage
cell walls stronger
energy store in seeds - fuels germination when the plant leaves the seed
