Question

Osmosis involves diffusion of ______.

पर्याय

• suspended particles from lower concentration to higher concentration.

• suspended particles from higher concentration to lower concentration.

• water from the more concentrated solution to the less concentrated solution.

• water from the less concentrated solution to the more concentrated solution.

Answer 1

Osmosis involves diffusion of water from the less concentrated solution to the more concentrated solution.

Explanation:

Osmosis is specifically the passive diffusion of solvent molecules (water) across a semi-permeable membrane. A less concentrated solution has fewer solute particles, which means it possesses a higher concentration of free water molecules. Consequently, water molecules naturally move down their own concentration gradient, moving from where water is abundant (less concentrated/dilute solution) to where water is less abundant (more concentrated solution) to achieve equilibrium.
