Detailed explanation-1: -The size of a cell is limited by the relationship of the cell’s outer surface area to its volume or its surface area-to-volume ratio. Thus, the correct answer is option A. Was this answer helpful?

Detailed explanation-2: -Cell size is limited by the surface area to volume ratio of the cell. As the volume of a cell increases, it becomes harder to efficiently transport materials in and out of the cell.

Detailed explanation-3: -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-4: -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-5: -Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
