Question
Chapter 36.2, Problem 2CC
Summary Introduction
To explain: The effect of reduction in the number of aquaporin channels on a plant cell’s capability to adjust according to osmotic conditions.
Concept introduction: Aquaporins are membrane channels, also known as plant proteins, which help in the transportation of water and neutral molecules through the plant cell plasma membranes. Aquaporins have many isoforms that have diverse cellular localizations, transport selectivity, and regulation properties.

How would a reduction in the number of aquaporinchannels affect a plant cell’s ability to adjust to newosmotic conditions?
1) A plant cell with a pressure potential of 5 bars and an osmotic potential of -9 bars is in equilibrium with a surrounding solution that is open to the air. What is the water potential of the surrounding solution?
2) A plant cell, when initially placed in pure water, has an osmotic potential of -4 bars and a pressure potential of +2 bars.
a) Which way will water diffuse?
b) When will net diffusion stop?
c) When equilibrium is reached, what are the cell's osmotic potential and pressure potential values?
Define the concept of osmotic
adjustment in root cells and how its
occurrence is of benefit to plant survival.
