Answer:
turgid = swollen
There is a limit to the amount of water that can enter the cell. The cell reaches this limit when the osmotic pressure attracting water into the vacuole is countered by the inward mechanical pressure exerted by the cell wall.
A turgid cell is a plant cell whose vacuole contains the maximum amount of water. The water has entered by osmosis, because the vacuole is hypertonic to the solution outside the cell.
Animal cells can swell so much from water that they burst, but plant cells avoid bursting thanks to their cell wall.
