MCQ
Diffusion of solvent through a semi permeable membrane is called
  • A
    Diffusion
  • Osmosis
  • C
    Active absorption
  • D
    Plasmolysis

Answer

Correct option: B.
Osmosis
b
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent). In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.
