What would enhance water uptake by a plant cell? a. decreasing the Ψ of the surrounding solution b. positive pressure on the surrounding solution c. the loss of solutes from the cell d. increasing the Ψ of the cytoplasm

Key Concepts

Water Potential (Ψ)

Water potential (Ψ) is a measure of the potential energy of water in a system, influencing the direction of water movement. It is composed of solute potential and pressure potential. A lower Ψ indicates a higher concentration of solutes, which can draw water into the cell, enhancing water uptake.

Osmosis

Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process is crucial for maintaining cell turgor and overall plant health, as it allows cells to absorb water efficiently.

Turgor Pressure

Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole of a plant cell against the cell wall. This pressure is essential for maintaining cell structure and rigidity. Increasing turgor pressure can enhance water uptake, as it creates a favorable gradient for osmosis.
