What does it mean when a plant is turgid?

Select one or more of the following:

The water has moved out the cell by osmosis, the cell decreases in volume and the cytoplasm no longer pushes against the cell wall. This makes the plant wilt. Excessive loss of water can cause the cell to become plasmolysed, when the membrane and cytoplasm split away from the wall
Water has moved into the plant cell by osmosis. The pressure increases inside the cell, the contents of the cell push against the wall which helps support the plant tissues.
