Question

If osmotic potwntial of a cell -10bars and its pressure potential isb5 bars

Answer 1

Answer:

Water potential is the sum of osmotic and pressure potential, given by the equation Ψ

W

W = Ψ

S

S + Ψ

P

P, where Ψ

W

W is the water potential, Ψ

S

S is the solute potential or osmotic potential and Ψ

P

P is the pressure potential.

Hence, if the osmotic potential of a cell is −10 bars and its pressure potential is 5 bars, its water potential would be,

Ψ

W

W = -10 + 5 = -5 bars. So, the correct option is '−5 bars'.
