Detailed explanation-1: -Osmosis is the movement of water molecules from its region of higher concentration to its region of lower concentration through a membrane.

Detailed explanation-2: -Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

Detailed explanation-3: -Osmosis is a movement of solvent particles or water from lower solute concentration to higher solute concentration through the semipermeable membrane. This process does not require energy. This requires a concentration gradient.
