Question

Movement of solvent molecule from a region of its higher concentration to a region of its lower concentration through a semi- permeable membrane is refferred to as
A. simple diffusion
B. facilitated diffusion
C. osmosis
D. active transport.

Answer 1

Correct Answer - C
When the two solutions having different osmotic concentrations are separated by means of a semipermeable membrane the molecules of solvent or water move from the region of their higher diffusion pressure (or free energy) to the region of their lower diffusion pressure (or free energy). This movement of water or solvent is called osmosis.
