As Cells Increase in Size

Question

As cells increase in size:
A) their surface/volume ratio increases, and they become more metabolically efficient.
B) their surface/volume ratio decreases, and they become more metabolically efficient.
C) their surface/volume ratio increases, and they become less metabolically efficient.
D) their surface/volume ratio decreases, and they become less metabolically efficient.

Accepted Answer

As cells increase in size, their volume increases at a faster rate than their surface area, resulting in a decreased surface/volume ratio. This means that there is less surface area available for essential processes such as gas and nutrient exchange, making the cell less metabolically efficient.
