Question

Water moves down an energy gradient. This can be represented by -

• A. Ψ = 0.2 to Ψ = -0.002
• B. Ψ = 0.001 to Ψ = -0.01
• C. Ψ = 0.02 to Ψ = -0.002
• D. Ψ = 0.1 to Ψ = 0

Answer 1

The correct option is B

Ψ = 0.001 to Ψ = -0.01

Water moves from higher water potential to lower water potential i.e., less negative to more negative value of water potential in cell systems which can promote ascent of water from roots to aerial parts of the plant.
