The pressure generated when water enters & inflates plant cells is called ___________ potential?
Correct answer: C. Pressure
- A. Water
- B. Osmotic
- C. Pressure
- D. Solute
Explanation
When water enters a plant cell, it pushes the plasma membrane against the cell wall and produces turgor pressure, represented as pressure potential. Students may choose b because entry of water is caused by osmotic effects, but the pressure generated inside the inflated cell is pressure potential.

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.
