Question

what is osmosis? ....​

Answer 1

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides

Answer 2

• "Osmosis is a process in which solvent molecules move from a low-concentration solution to a high-concentration solution over a semi-permeable membrane."
• Osmosis is an energy-free process. It entails moving molecules from a higher-concentration zone to a lower-concentration region until the concentrations on both sides of the membrane are equal.
• Gases and supercritical liquids can all go via the osmosis process.
