Water potential is determined by which of the following?

As a result of endosmosis,$\psi_{w}$ of a cell:

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:

When water is lost through transpiration from the leaves, what happens to the water potential of the leaf cells?

What is the relationship between pure water and water potential?

Select the correct option based on the experiment shown below.
