Question

Which of the following would not contribute to water uptake by plant cell?

• A. an increase in the water potential $\Psi$ of the surrounding solution
• B. a decrease in pressure on the cell exerted by the wall
• C. the uptake of solutes by the cell
• D. an increase in tension on the surrounding solution.

Answer 1

The correct option is A an increase in the water potential $\Psi$ of the surrounding solution

Plant absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it's used for different purposes. It's a reactant used in photosynthesis.

So, the correct option is 'an increase in the water potential of the surrounding solution.'
