Question

Why do some plants remove water from their cells to reduce the amount of water that freezes inside them during winter?

a. The frozen water constricts organelles and causes plant cells to shrink.

b. As water contracts during freezing, the cells pull away from each other causing damage.

c. Less water in the cells means the cells are smaller and need to do less work.

d. The expansion of water as it turns to ice inside the cells would break the cells apart.

Answer 1

`\Large \boxed{\sf D}`

The cells would split apart due to the expansion of extra water when it freezes inside them. The liquid inside the cells can freeze and expand when the temperature drops below 0°C. The crop becomes unproductive as a result of the cells breaking.

Answer 2

b. As water contract during freezing the cells pull away from each other causing damage
