Question

Osmosis is the movement of

• A. Solute particles from lower concentration to higher concentration through a semi-permeable membrane.
• B. Solvent particles from higher water potential to lower water potential through a semi-permeable membrane
• C. Solute particles from higher concentration to lower concentration through a semipermeable membrane
• D. Solvent particles from lower water potential to higher water potential

Answer 1

The correct option is B Solvent particles from higher water potential to lower water potential through a semi-permeable membrane

Osmosis is the flow of solvent molecules from the region of higher water potential to the region of lower water potential through a semipermeable membrane. The osmotic entry of water (solvent) into a cell, organ or system is called endosmosis while the osmotic withdrawl of water from the same is described as exosmosis
