D)cell membrane strength

Question

Quizplus · Accepted Answer

The main limitation on cell size is diffusion, as larger cells have more difficulty obtaining nutrients and eliminating waste products through simple diffusion alone. This is because larger cells have a smaller surface area to volume ratio, and as a result, the distance for diffusion becomes too great for efficient exchange. Bulk flow and oxygen availability may also be factors, but they are not the main limiting factor for cell size. Cell membrane strength may limit the size of a cell, but it is secondary to the diffusion limitation.
