Which of the following is true of the water potential of a healthy living plant cell? ( SELECT ALL THAT APPLY) A. It has a higher solute potential (lower solute concentration) than the extracellular environment B. It is under negative pressure C. It has a lower solute potential (high solute concentration) than the extracellular enviroment D. It is under positive pressure E. It has a pressure potential equal to zero
Increasing 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.
This apparatus was used by a student, in a brightly lit room, to measure the rate of water
loss from a leafy shoot. He measured how far the bubble moved in five minutes. He
measured this three times.
The results are shown in the table.
