Question

question 3
when plant cells are in a hypotonic medium, they
a undergo plasmolysis (plant cell shrinking)
b build up turgor pressure
c wilt
d decrease pinocytosis
e lose water to the environment

Explanation:

In a hypotonic medium, the solute concentration outside the plant cell is lower than inside. Water moves into the plant cell by osmosis. The cell wall of the plant cell prevents it from bursting, and as water enters, turgor pressure builds up. Plasmolysis occurs in hypertonic media, wilting is related to water - loss (not gain as in hypotonic), pinocytosis is a form of endocytosis not directly related to this osmotic situation, and water moves into the cell not out in a hypotonic medium.

Answer:

B. Build up turgor pressure
