1 CELL PHYSIOLOGY EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ How big is a typical human cell and can you see it with the naked eye? Correct Answer: 10 um and no Why is a cell roughly 10 um? Correct Answer: This size allows the cell to effectively communicate with its environment through its plasma membrane. What would happen if a cell got bigger than 10um? Correct Answer: cell's membrane would not be able to efficiently communicate with its environment due ...
