Based on the figure given below which of the following statements is not correct?
a. Movement of solvent molecules will take place from chamber A to B.
b. Movement of solute will take place from A to B.
c. Presence of a semipermeable is a pre-requisite for this process to occur.
d. The direction and rate of osmosis depend on both the pressure gradient and concentration gradient.

Solution:

Option (b) is the answer.

Because the water in chamber A contains fewer solute particles, the water potential in chamber A is higher, allowing the water molecules in chamber A to move more freely. As a result, the solvent or water molecules will migrate from chamber A to chamber B. The solute molecules cannot migrate from chamber A to chamber B or from chamber B to chamber A because the membrane between the compartments is semi-permeable.
