Detailed explanation-1: -Osmosis is the process of moving solvent particles across a semipermeable membrane from the solvent’s higher concentration to the solvent’s lower concentration. The complete process does not require energy to take place. For example, the absorption of water molecules from the soil through the roots of the plant.

Detailed explanation-2: -When people discuss osmosis in biology, it always refers to the movement of water. In chemistry, it’s possible for other solvents to be involved. In biology, this is a difference between the two processes.

Detailed explanation-3: -Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.

Detailed explanation-4: -Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.

Detailed explanation-5: -Osmosis is the flow of solvent molecules from the region of higher water potential to the region of lower water potential through a semipermeable membrane. The osmotic entry of water (solvent) into a cell, organ or system is called endosmosis while the osmotic withdrawl of water from the same is described as exosmosis.
