atmosphere. (20 marks)​

Answer 1

1-Water is passively transported into the roots and then into the xylem.

2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem.

3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.
