Question

(i) ${\Psi }_P$ will be positive
(ii) Cell 'B' is flaccid.
(iii) ${\Psi }_W$ of cell 'A' is minimum
(iv) ${\Psi }_P$ of cell 'C' would be zero.
How many above statements are correct with repect to diagram ?

• A. One
• B. Two
• C. Four
• D. Three

Answer 1

The correct option is D Three

The given diagram represents the plasmolysis.

Cell A is placed in hypertonic solution. Cell B shows incipient plasmolysis and cell C shows complete plasmolysis. So, in the cell B & Cwater potential osmotic potential and pressure potential decreases. So

(i)Ѱ_{P will be positive - true}

(ii) Cell B is flaccid - true

(iii) Ѱ_w of cell 'A' is minimum - false

(iv) Ѱp of cell 'C; would be zero - True

So the correct option is 'three'.
