Question 22 • IL-Science 7 A

Which best describes what happens when a cell shrinks and shrivels due to osmosis?

Answer
A
Water molecules are too large to move across the cell membrane into the cell.
B
Water molecules move out of a cell from high concentration to low concentration.
C
Water molecules fill the inside of a cell and tighten the cell membrane.
D
Water molecules react with the cell membrane and cause it to break apart.

Explanation

A cell shrivels when it loses water by osmosis. Water moves across the membrane from an area of higher water concentration to an area of lower water concentration, so a net movement of water out of the cell makes it shrink. Choice B describes this movement.
