Solutions and Cells

Question 1

What effect does a hypertonic solution have on animal cells?

Answer 1

Animal cells lose water and may undergo crenation

Crenation refers to the shriveling of cells.

Question 2

What effect does a hypotonic solution have on animal cells?

Answer 2

Animal cells gain water and may undergo lysis

Lysis refers to the bursting of cells due to excessive water intake.

Question 3

What effect does an isotonic solution have on animal cells?

Answer 3

Animal cells maintain their normal shape and volume

There is no net movement of water in isotonic conditions.

Question 4

What effect does a hypertonic solution have on plant cells?

Answer 4

Plant cells experience plasmolysis, where the cell membrane pulls away from the cell wall

Plasmolysis can lead to wilting in plants.

Question 5

What effect does a hypotonic solution have on plant cells?

Answer 5

Plant cells gain water and become turgid, maintaining structure

Turgidity is important for plant stability and growth.

Question 6

What effect does an isotonic solution have on plant cells?

Answer 6

Plant cells maintain their shape but are not as firm as in hypotonic solutions

Isotonic conditions do not provide the same structural support as turgidity.

Question 7

True or False: Hypertonic solutions cause cells to swell.

Answer 7

False

Hypertonic solutions cause cells to shrink.

Question 8

Fill in the blank: A solution that causes cells to lose water is called a _______.

Answer 8

hypertonic solution

Hypertonic solutions have a higher solute concentration.

Question 9

Fill in the blank: A solution that causes plant cells to become turgid is called a _______.

Answer 9

hypotonic solution

Hypotonic solutions have a lower solute concentration.
