Question 3
Cell and Its EnvironmentWhich of the following statements is not true of osmotic process?
- A.There must be a selectively permeable membrane
- B.The two solutions must be of different concentrations initially
- C.It involves only the movement of water molecules
- D.Equilibrium is reached when there is equal distribution of water molecules
- E.The two solutions are of equal concentration at the beginning of experiment
Show the answer and explanation
Answer: E (The two solutions are of equal concentration at the beginning of experiment)
Explanation
Osmosis needs a difference in concentration; if both solutions start equal there is no net movement of water.
