What does hyper-osmotic mean?

If a solution has a higher osmotic potential, it draws water out of the cells. The solution is hyper-osmotic.

A solution that is hyper-osmotic or hypertonic has a higher osmotic potential and contains more solutes. It therefore draws water across membranes from areas with lower osmotic potential (hypo-osmotic). In this example, if you dropped some cells in a hyper-osmotic solution it would draw the water out of the cells making them crenate.

I've heard the term water potential used before but was never taught using it, so I don't really know what it means. See if it matches up with any of that.

As in the title.

I'm making notes from a lecture and I see this:




I'm confused here.

Firstly, does water potential = osmotic potential? In that case, water moves from a high potential to a low potential.

Secondly, if a solution has a higher osmotic potential, shouldn't that mean that water actually goes into the cell, as opposed to water being drawn out of the cell?

Many thanks
