Question
Two cells, A and B beside each other in the root cortex. ψs and ψp values of cell A are - 0.8 MPa and 0.6 MPa. ψs and ψp of cell B are -0.7MPa and 0.4 MPa. Water moves from ______.
Answer: Option A
:
A
ψw of cell A = -0.8+0.6 = - 0.2 MPa ψ of cell B = -0.7+0.4= - 0.3 MPa. Water moves from higher ψw value to lower Ψw value. Hence it moves from A to B
