The negative water potential of plant cells that is necessary for water uptake must become even more negative in _______ and _______ environments.

Question

Quizplus · Accepted Answer

In saline environments, the presence of solutes outside the plant cells decreases the water potential of the surrounding solution. Therefore, the water potential of plant cells must become even more negative to create a gradient for water uptake. In dry environments, the water potential of the soil is low due to evaporation and lack of rain, which also requires plant cells to maintain a more negative water potential for water uptake.
