The correct ascending sequence with respect to their water potential is
`I. pi= - 0.8 " Mpa," P= +0.4 " Mpa"`
II `pi= -1.0` Mp a, P=+ 0.5 MP a
`III. Pi`=-0.9 MP a, P = +0.2 MP a
IV. `pi`=-0.3 MP a, P= + 0.2 MP a

Options

A. I,II,III, IV
B. III,II, I,IV
C. III,I,II,IV
D. III,IV,II,I

Answer

B

Explanation

The correct ascending sequence of cells with respect to their water potential is III, II, I and IV.
Because water potential `(Psi_(w))=pi` (solute potential)+P(pressure potential)
