Question

Under given suitable conditions, the DPD will be more than OP

• A. When OP is equal to TP
• B. When OP is less than TP
• C. When OP is greater than TP
• D. When TP is negative

Answer 1

Answer: (D)

When TP is negative

DPD = OP - TP
Mathematically expressed diffusion pressure deficit (DPD) is equal to the difference of osmotic pressure (OP) and turgor pressure (TP). When T.P is negative, DPD will be more than OP. So, D.P.D. of a cell mainly depends upon OP.
