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.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
