Question #15324

Answer 1

Sucrose `(C_12H_22O_11)`

Explanation:

Using `ATP`, the plant moves in sucrose made in the leaves and through the phloem using active transport, since the sucrose moves up the concentration gradient.

This movement is done by pressure flow hypothesis, and you can read about it here:
