Question

Which of the following statements is true about the process of osmosis?

• A. Osmosis involves the movement of solute molecules from low to high concentration.
• B. Osmosis does not require energy input.
• C. Osmosis occurs only in plant cells.
• D. Osmosis involves the movement of water molecules from high to low concentration.

Hint:

Osmosis is a passive process that moves water across membranes without the need for energy, driven by differences in solute concentration.

Answer 1

The Correct Option is D

Osmosis is the passive movement of water molecules through a selectively permeable membrane, from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration). This process does not require energy, as it is a type of diffusion. Osmosis is critical for maintaining proper fluid balance in cells and organisms, allowing water to move into or out of cells based on the concentration of solutes inside and outside the cell. Thus, osmosis involves the movement of water molecules from high to low concentration.
