Q10 / 164 · NTA Abhyas (NEET) 2020 · Botany · Transport in Plants

Select the correct statement from the following.

  • A
    Osmotic pressure is the negative pressure applied on hypertonic solution to stop osmosis.
  • B
    Osmotic potential is positive.
  • Correct answer
    C
    More is the solute concentration of solution, more will be the pressure required to prevent water from diffusing in.
  • D
    The net direction and the rate of osmosis does not depend on the pressure gradient nor on concentration gradient.

Solution

Osmotic pressure is the positive pressure applied on hypertonic solution to stop osmosis. Osmotic potential is negative, and represents decrease in free energy of the solution on addition of solute. More the solute concentration of solution, more will be the pressure required to prevent water from diffusing in, thus more will be the osmotic pressure.

Hence, the correct answer is option: 'C'.
