What happens when the concentration of solutes decrease in the guard cells?

Apoplast is the system of adjacent cell walls that is continuous throughout the plant except at the 

During its life, a potato plant transpires water

Value of osmotic potential $$ ( \pi ) $$ and pressure potential (p) of cells a, b, c, d are given: 

The phenomenon of osmosis is involved in the diffusion of water from

Solution A has $$ \Psi_s = -30 $$ bars and $$ \Psi_p = 5 $$ bars. Solution B has $$ \Psi_s = -10 $$ bars and $$ \Psi_p = 0 $$ atm. The two are separated by semipermeable membrane. Flow of water will be 

Water potential in closely placed cell (p, q, r) is given below. Find out correct direction of water movement : 

Cell a and cell b are adjacent plant cells. In cell a $$ \Psi_s = -20 $$ bars and $$ \Psi_p = 8 $$ bars. In cell b $$ \Psi_s = -12 $$ bars and $$ \Psi_p = 2 $$ bars. Then:
