8. What must occur for osmotic forces

to cease across a cell membrane?

A. Equilibrium. B. Diffusion.

C. Dehydration

D. Active transport.

Osmotic force results in the movement of solvent from a region of high concentration to that of a lower concentration through a semi-permeable membrane.

For osmotic force two be set up, the two system of solvent must be at different concentration. When the solvents have a uniform concentration, osmotic force ceases.

Therefore, a system in which no change in concentration occurs is an equilibrium system. Such a system has no osmotic force.
