Question

If plants do not get watered, they will start to wilt because their central vacuoles are empty. When they get water again, they will stand back up because their vacuoles have filled back up. What process allows their vacuoles to fill back up with water? *

Answer 1

Answer:

osmosis

Explanation:

The process that allows the vacuoles of plants to fill back up with water after a period of wilting is osmosis.

Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane. Water enters the vacuoles of plants osmotically once water becomes available in their cells.

The availability of water in the cytosol makes it to have a higher water potential than the cell sap. In this case, the vacuole membrane or the tonoplast acts as the semi-permeable membrane and allows water to diffuse into the vacuole.
