Question

Choose the correct answers from the alternatives given :
Water potential is affected by

• A. osmotic potential
• B. matric potential
• C. pressure potential
• D. all of these

Answer 1

The correct option is D all of these

• Water potential is the potential energy of water relative to pure water in a plant cell or tissue. This can be written as the sum of matrix potential (due to binding of water to cell and cytoplasm), the solute potential (due to concentration of dissolved solutes which by its effect on the entropy components reduces the water potential) and pressure potential (due to hydrostatic pressure, which by its effect on energy components increases the water potential).
  
• Ψw = Ψs + Ψp + Ψm
  
• So the correct answer is "All of these".
