Question

in cold temperatures ice can kill plants if it is formed ______.
a. inside the bark
b. on the surface of the leaves
c. inside the plant cells
d. between the cell walls

Explanation:

To determine the correct answer, we analyze the effect of ice formation on plant cells. When ice forms inside plant cells (option c), it can damage the cell structure by expanding and rupturing the cell membranes/organelles, which is lethal to the plant. Ice on the leaf surface (b) or between cell walls (d) or inside bark (a) generally doesn't cause the same level of internal cellular damage that kills the plant.

Answer:

c. inside the plant cells
