Food Transport in Plants

Food transport is an active process because ATP is needed.

This can move up or down the stem

Food is transported in the sieve tube elements of the phloem

Phloem sap is a solution of sugar

Sugar made in the leaves by photosynthesis is transported to the growing points.

Excess is often sent to the roots for storage

At the start of the growing season the food is transported from the storage regions to the growing points
