Osmosis

Q. The movement of water through a semi-permeable membrane from a region of its higher concentration to a region of its lower concentration is specifically called:

1. Osmosis
2. Active Transport
3. Imbibition
4. Diffusion

Q. Osmosis is the movement of

1. Solute particles from lower concentration to higher concentration through a semi-permeable membrane.
2. Solvent particles from higher water potential to lower water potential through a semi-permeable membrane
