Detailed explanation-1: -Osmosis occurs according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. Osmosis occurs until the concentration gradient of water goes to zero or until the hydrostatic pressure of the water balances the osmotic pressure.

Detailed explanation-2: -Osmosis & Concentration Gradient An osmosis concentration gradient drives the movement of water from the side of the membrane with a greater concentration of water to the side with a lower concentration of water.

Detailed explanation-3: -A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.

Detailed explanation-4: -The osmotic gradient is the difference in concentration between two solutions on either side of a semipermeable membrane, and is used to tell the difference in percentages of the concentration of a specific particle dissolved in a solution.
