Question

What forces are responsible for the movement of water in plants from roots to tree tops?

Answer 1

Answer:

In plants, the transpiration stream is the uninterrupted stream of water and solutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast-interface of the substomatal cavity. It is driven by capillary action and in some plants by root pressure.

Explanation:

Answer 2
