- Compared with a cell with few aquaporin proteins in itsmembrane, a cell containing many aquaporin proteins will(A) have a faster rate of osmosis.(B) have a lower water potential.(C) have a higher water potential.(D) accumulate water by active transport.arrow_forwardIncreasing the concentration of solutes increases osmotic potential, hence water potential decreases. A. Agree, because presence of solutes increses osmotic pressure and thus osmotic potential. C. Agree, because they just represent the same values. D. Disagree, because it is the decrease in water pressure that decreases osmotic potential. B. Disagree, because presence of solutes increases osmotic pressure which decreases osmotic potential.arrow_forwardDifferentiate between the following types of movement observed on a wet mount or hanging drop slide:a. directional motility.b.
