Q

How are salts taken up?

A

By active transport. Active transport can collect salts against a concentration gradient. This needs energy from respiration.

Q

Where does food in a plant end up?(5)

A
  • sugars are changed into starch and stored in the root cortex and in seeds
  • sugars also form cellulose for new cell walls at the growing root tip and shoot tip
  • sugars are also transported to the fruits.
  • amino acids make proteins needed to make new cells
  • fatty acids form fats that are stored in many seeds
