Different cells have somewhat different plasma membranes. The plasma membrane of a Paramecium, for example, is only about 1% as permeable to water as the plasma membrane of a human red blood cell. Hypothesize about why this is the case. Is Paramecium likely to have aquaporins in its plasma membrane? Explain your answer.
