Question

Osmosis involves

• A. Diffusion of suspended particles from higher to lower concentration.
• B. Diffusion of suspended particles from lower to higher concentration.
• C. Diffusion of water from more to less concentrated side.
• D. Diffusion of water from less to more concentrated side.

Answer 1

The correct option is D Diffusion of water from less to more concentrated side.

Osmosis is the process of movement of molecules from the region of higher concentration of solvent or lower concentration of solute to the lower concentration of solvent or higher concentration of solute through a semipermeable membrane. On absorption of water the turgor pressure inside the cells increases. It helps to maintain the shape of the cell. It helps in the growth, development, mechanical support and prevents wilting.

So, the correct answer is option D.
