Water crosses the membrane from dilute to concentrated

For osmosis, track water—not solute—across a semi-permeable membrane. The concentration difference determines the net direction.

Psi-water equals psi-solute plus psi-pressure.

Water potential is the sum of solute and pressure components:

Ψw = Ψs + Ψp

Given Ψw = -1600 kPa and Ψs = -2000 kPa, Ψp = -1600 - (-2000) = +400 kPa

Keep the pattern precise

Read the conditions in the stem carefully and use the stated model, labels, or assumptions before choosing an answer.
