Which ratio limits the size of cells?
|
The rate of metabolism to mass
|
|
The surface area to volume
|
|
The mass to volume
|
|
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.
