Question

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. A) increases; harder B) decreases; more difficult C) decreases; less difficult D) increases; use active transport

Answer 1

The answer is B. decreases; more difficult.
Hope this helps :)

Answer 2

Answer: The correct answer would be option B.

Explanation:

Increase in volume results in decrease in area/volume ratio.

Area/volume ratio plays important role in efficiency of diffusion. Higher the area/volume higher the efficiency and lower the ratio lower will be the efficiency.

A high area/volume ratio means that a cell has higher surface as compared to its volume or cellular content. Thus, it can easily diffuse or exchange its content with the surrounding.

For example, microvilli in small intestine have high area/volume ratio due to which they are highly efficient in absorbing nutrients.

Thus, the correct answer would be option B.
