Define osmosis?

  

Answers


Francis
Osmosis is a process by which solvent molecules move from a region of high concentration (dilute solution) to a region of low concentration (concentrated solution) through a semi permeable membrane.
Osmosis can be described as a special type of diffusion since it involves movement of solvent (Water) particles from a region of high concentration to a region of low concentration.
