Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which ratio limits the size of cells?
A
The rate of metabolism to mass
B
The surface area to volume
C
The mass to volume
D
The volume to surface area
Explanation: 

Detailed explanation-1: -Answer: The surface area to volume ratio (SA:V) limits cell size because the bigger the cell gets, the less surface area it has for its size.

Detailed explanation-2: -What limits cell sizes and growth rates? Cell growth is limited by rates of protein synthesis, by the folding rates of its slowest proteins, and-for large cells-by the rates of its protein diffusion.

Detailed explanation-3: -Seeing that the surface area to volume ratio of cells generally decreases as cells get larger, making the exchange of resources, waster and heat more and more difficult.
