Osmosis drives water through membranes toward higher solute concentration
Solute gradients push solvent molecules to equalize concentrations across barriers
Osmosis is the spontaneous net movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration. Water molecules diffuse down their concentration gradient until osmotic equilibrium is established. Plants rely on osmotic pressure in root cells to draw water from surrounding soil against gravity.

Osmosis drives water through membranes toward higher solute concentration: the short answers
- Where does this come from, and can I check it?
- Solute gradients push solvent molecules to equalize concentrations across barriers. The figure is taken from Encyclopaedia Britannica, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a science fact?
- Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
