Question

Water potential of a cell becomes zero when it is in

• A. Turgid state
• B. Flaccid state
• C. Incipiently plasmolysed state
• D. Completely plasmolysed state

Answer 1

The correct option is A Turgid state

Water potential depends on the concentration of water molecules in a system. More the number of water molecules more the water potential in the system. Water always flow from a region of higher to lower water potential. The maximum value of water potential is zero. Hence, when water potential is zero water will not move into the cell and the cell will be called as a turgid cell.

So, the correct answer is option A.
