When an Animal Cell Is Placed in a Hypotonic Solution

question 41

Multiple Choice

When an animal cell is placed in a hypotonic solution and water enters the cell via osmosis, the volume of the cell increases until it bursts. This does not happen to plant cells, because

• A) they have large central vacuoles, which provide abundant space for storage of incoming water.
• B) they have cell walls, which prevent the entry of water by osmosis.
• C) they have cell walls, which provide pressure to counteract the pressure of the incoming water.
• D) certain proteins embedded in their plasma membranes act as "check valves," releasing excess water before it can cause the cell to burst.
• E) the composition of their plasma membranes differs from that of animal- cell plasma membranes in a way that provides much greater strength.
