Water Relations of Plants · NCERT Biology

Which factor does NOT directly affect plasmolysis?

  1. Concentration of external solution
  2. Permeability of plasma membrane
  3. Temperature of the solution
  4. Ambient light intensity
Show answer and explanation

Correct answer: Ambient light intensity

Plasmolysis depends on the osmotic gradient (external solute concentration), membrane permeability, and temperature. Ambient light intensity does not directly influence osmotic water movement across the membrane.
