Pressure potential is usually ........... and it is denoted as

The water potential of seawater is $...........$.

Water potential is affected by

The movement of water molecules from a root cell to the adjacent cortical cell occurs based on what?

Cell $A$ has an osmotic pressure of $-20$ bars and a pressure potential of $5$ bars, whereas cell $B$ has an osmotic pressure of $-18$ bars and a pressure potential of $2$ bars. The direction of the flow of water will be:

Why is solute potential always negative? Explain $\Psi_{w} = \Psi_{s} + \Psi_{p}$.
