Question

In a solution of salt and water, if the concentration of salt molecules is greater outside a cell than inside, then water molecules will __________.

A.
move into the cell, and the cell will shrivel

B.
move into the cell, and the cell will burst

C.
move out of the cell, and the cell will shrivel

D.
move out of the cell, and the cell will burst

Answer 1

When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration.

For example, if the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell.

If water moves out of a cell, it will shrivel.
Like if you have a plant and there is not enough water, your plant will become flaccid and shrivel.

It's all about osmosis.
