Question

Different Plants can open and close their flowers and leaves. Scientists say they do it by moving water inside their bodies. Explain how?

Answer 1

Explanation:

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.
