Normally, in the process of osmosis, the net flow of water molecules into or out of the cell depends upon differences in the ?

Correct answer: A. Concentration of water molecules inside and outside the cell

  • A. Concentration of water molecules inside and outside the cell
  • B. Concentration of enzymes on either side of the cell membrane
  • C. Rate of molecular motion on either side of the cell membrane
  • D. None of these

Explanation

Osmosis is the net movement of water across a selectively permeable membrane, driven by a difference in water concentration on the two sides. Option c is a likely distractor because temperature affects molecular motion, but the defining factor in osmosis is the water concentration gradient.
