The surface area/volume ratio is an important factor for one-celled organisms. As a cell's volume grows, its surface area/volume ratio __________, making it ______________ to acquire enough nutrients via diffusion.

The two words that go in the blanks I would guess they are looking for are "decreases" and "difficult".

Correct answer: Decreases, Difficult

As the cell continues to grow, its internal volume increases and its membrane expands. At a certain time, there is a situation when the volume of a cell increases more as compared to the surface area. As a result of that the surface area volume of cell decreases. As the surface area to volume ration decrease, the cell becomes larger.

Hence, as the cell continues to grow beyond a limit, all the material are not able to cross the membrane rapidly so that it maintains the increased cellular volume. It results to disturb the normal function of a cell.
