What is Osmosis?

Osmosis is the movement of water from a high concentration to a low concentration across a partially permeable membrane.

Hi Jagjot Gill,

Osmosis is simply the movement of water from one side of a membrane to the other. This movement is passive, meaning that it requires no energy, as it occurs from an area of high water potential (think of this as the 'concentration of water') to an area of low water potential.

Osmosis is the passive movement of water from a high concentration to a low concentration, across a partially permeable membrane.

Osmosis is the movement of water from an area of high water potential to an area of low water potential across a partially permeable membrane. It is essentially the diffusion of water molecules but when we talk about water we don't call it diffusion we call it osmosis
