Question

question 8 of 10
the following models show one large cell (a) and four small cells (b).
which of the following states why one of the models is better for moving more nutrients in and out of the cell?
a. b is better because it has more surface area.
b. a is better because it has more surface area.
c. b is better because it has less volume.
d. a is better because it has less volume.

Explanation:

The rate of movement of nutrients in and out of a cell depends on the surface - area - to - volume ratio. Smaller cells or a group of smaller cells (like model B) have a larger total surface area compared to a single large cell (model A) of the same total volume. A larger surface area allows for more efficient exchange of nutrients and waste across the cell membrane.

Answer:

A. B is better because it has more surface area.
