Show answer Hide answer
Answer
The starch is food made in the leaves and carried to the potato by the phloem.

Explanation

  • Food is made in the leaves by photosynthesis.
  • It is made as glucose and changed into starch for storage.
  • The phloem carries this food from the leaves to the potato.
  • The potato is an underground part where food is stored.
Leaves make the food; the phloem carries it to the potato to store.
