Following are a few definitions of osmosis. Read carefully and select the correct definition.
(a) Movement of water molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane
(b) Movement of solvent molecules from its higher concentration to lower concentration
(c) Movement of solvent molecules from higher concentration to lower concentration of solution through a permeable membrane
(d) Movement of solute molecules from lower concentration to higher concentration of solution through a semi-permeable membrane.
Correct Answer: (a) Movement of water molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane
Explanation:
Osmosis is the process of movement of water from a region of higher water concentration to a region of lower water concentration. Osmosis involves the movement of water molecules, while diffusion involves the movement of solute particles across a concentration gradient.
Also, osmosis involves the presence of a semi-permeable membrane to allow the selective movement of only water molecules and not solute particles.
