all of these are factors

Detailed explanation-1: -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-2: -The single factor that limits the size of most of the cell is the surface volume ratio. The size of the cell gets limited by the nucleo-cytoplasmic ratio, which determines the range of control of metabolic ratio and the ratio of surface to volume.
Detailed explanation-3: -A cell must have enough surface area to bring in nutrients and export wastes from its entire volume. However, the ratio of surface area to volume decreases as a cell becomes larger. This places a limit on the largest size that a cell can be.
