Which Best describes how water moves during osmosis? From low salute concentration to high salute concentration

Complete question: Which Best describes how water moves during osmosis?

A. From passive transport regions to active transport regions

B. From active transport regions to passive transport regions

C. From high solute concentration to low solute concentration

D. From low solute concentration to high solute concentration

The correct option is D(From low solute concentration to high solute concentration)

Explanation:

Osmosis can be defined as the thermal movement of water molecules through a selectively permeable or semi-permeable membrane.

A selectively (differentially) permeable membrane will only allow certain molecules to pass through it. Water molecules can pass through a selectively permeable membrane easily but solutes(for example, sugar molecules) cannot.

Using sugar solution to explain further, the following occurs when equal volume of a weak( low solute concentration) and a strong sugar solution( high solute concentration) are separated by a selectively permeable membrane. A diffusion gradient exists between the water molecules in the two solutions. As a result, water molecules move from the low solute concentration to high solute concentration through the membrane. This water movement continues untill there is equal concentration of sugar on the both sides of the membrane.
