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?
What is the relationship between osmotic potential and plants when water with salinated water is used to water plants?
E.G: How does it inhibit growth and why if the plant isn't salt tolerant
Explain what would happen if a plant cell was placed in a hypotonic environment and why (be sure to include solute concentrations, water movement and turgor pressure in your explanation)?
