An increase in cell size results in an increase in surface area to volume ration.

a. true

b. false

False.

Explanation:

The prokaryotes are smaller in size and has large surface area to volume ratio. This high surface area volume ratio increases the rate of diffusion in case of prokaryotes.

The ratio can be obtained by dividing the surface area to the volume. This signifies that how much surface area is available in comparison the volume of the cell. The large cell has large volume. This means the ratio is inversely proportional to the cell size or volume. Hence, the large cell has small ratio of surface area to volume.

Thus, the correct answer is option (b).
