NEET · BiologyHard
A plant cell with a solute potential of and a pressure potential of is placed in a solution with a water potential of . What is the direction of net water movement and the final state of the cell?
- A.Water moves into the cell, cell becomes turgid
- B.Water moves out of the cell, cell becomes flaccid
- C.Water moves into the cell, cell becomes plasmolyzed
- D.No net movement, cell remains at equilibrium
Show correct answer & step-by-step solution
Correct answer: A — Water moves into the cell, cell becomes turgid
Solution
- Calculate the cell water potential using .
- Substitute the values: .
- Compare the cell water potential () with the external solution ().
- Since , water moves from the solution into the cell.
- Hence the answer is (A).
