Options

A. R and S
B. P and R
C. Q and S
D. P and Q

Answer

B

Explanation

Turgor pressure is the hydrostatic pressure in excess of ambient atmospheric pressure which can build up in living walled cells. Turgor is generated through the osmotically driven inflow of water into the cell across a selectively permeable membrane. In cell P and R water moves outside of the cell and cell shrink.
