The process where water leaves a plant cell is called osmosis.

Here's a breakdown:

* Osmosis is the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration.

* In a plant cell, the cell membrane and the cell wall act as semipermeable membranes.

* When the concentration of water outside the cell is lower than inside the cell, water moves out of the cell through osmosis. This can happen when the plant is under stress, such as drought or high salinity.
