Question

Swelling of guard cells and movement of sugars by the pressure-flow mechanism both depend on the fact that ___ can move across cell membranes from areas of high concentration to areas of low concentration.

Answer 1

Step-by-step explanation:

the answer is water. This is because through the process of osmosis, water moves from areas of high concentration to areas of lower concentration, and this is what occurs on the cell membrane when the swelling of guard cells causes the stoma to open.
