Diffusion occurs from a region of lower concentration to higher concentration.
Movement of molecules of a substance from the region of their higher concentration to the region of their lower concentration without the involvement of a separating membrane is called
(a) Osmosis (b) Diffusion
(c) Active transport (d) Capillarity
The movement of substances from a region of higher concentration to a region of lower concentration is called :
Diffusion is based on the tendency of molecules to move from a higher concentration to a lower concentration. This process requires assistance in form of energy.
Question 6 Which among the following defines osmosis the best? (a) Movement of water molecules from a region of higher concentration to a region of lower solute concentration through a semipermeable membrane (b) Movement of solvent molecules from its higher concentration to a lower concentration (c) Movement of solvent molecules from a higher concentration to a lower concentration of solution through a permeable membrane (d) Movement of solute molecules from a lower concentration to a higher concentration of a solution through a semipermeable membrane
