Question

What is the best description of osmosis?

Answer 1

Net movement of molecules across the nuclear membrane until the number of molecules on each side is nearly equal

Explanation:

The net spontaneous movement of the molecules of a solvent  through the selective membrane to an area of higher concentration of the solvent is the process of Osmosis.  

By this process in a solvent separates the 2 solutions of various concentrations. The pressure through which the movements were initiated is the ‘osmotic pressure’. The membrane should be permeable for molecule movements.

Answer 2

Answer:

Movement of water from an area of lower solute concentration to an area of higher solute concentration

Explanation:

Osmosis is movement of only WATER. Diffusion would be the moving of any other substance other than water.
