Osmosis is the movement of water across membranes to balance solute concentrations. Water diffuses from a solution that is hypotonic into a solution that is hypertonic

Turgor pressure is the hydrostatic pressure that increases as water enters plant cells.

Animal cells lack cell walls and do not experience turgor pressure.

Plant cell walls restrict the extent to which cells can expand, hence the pressure on the cell wall increases as more water enters the cell.

RWC, is a measure of turgidity and hence the water content of plants

In arid conditions, RWC values of less than 50% cause most plants to die

whereas values closer to 100% indicate plants are less affected by drought stress.
