E)as a result of all of these conditions.

Question

Quizplus · Accepted Answer

When a plant with flexible cell walls is placed in a hypertonic solution, water moves out of the cells causing them to lose turgor pressure and wilt. This is because the concentration of solutes outside the cell is higher than inside the cell and water moves from high to low concentration. Isotonic solution and facilitated diffusion do not directly affect the turgor pressure of the cell, and a rise in turgor pressure would not cause wilting.
