Question

part b: matching

1. ____ solution with a lower solute concentration (more water)
2. ____ solution in which the solute concentration is the same
3. ____ condition plant cells require
4. ____ condition that animal cells require
5. ____ red blood cells bursts (cytolysis)
6. ____ plant shrinks (plasmolysis)
7. ____ solution with a higher solute concentration (less water)

word bank
a) isotonic
b) hypertonic
c) hypotonic
d) lyse
e) plasmolysis

Explanation:

1. A hypotonic solution has lower solute (more water) concentration.
2. Isotonic solutions have equal solute concentrations.
3. Plant cells need hypotonic conditions to stay turgid.
4. Animal cells need isotonic conditions to avoid damage.
5. Red blood cells undergo cytolysis (burst) in hypotonic solutions, described as lyse.
6. Plant cells shrink via plasmolysis in hypertonic solutions.
7. A hypertonic solution has higher solute (less water) concentration.

Answer:

1. C) Hypotonic
2. A) Isotonic
3. C) Hypotonic
4. A) Isotonic
5. D) Lyse
6. E) Plasmolysis
7. B) Hypertonic
