A plant cell becomes turgid due to
plasmolysis
exosmosis
endosmosis

endosmosis
Osmosis is the diffusion of water molecules through a differentially permeable membrane. Endosmosis leads to diffusion of water into the cell and thus, cell becomes turgid.
Plasmolysis is the shrinking of protoplasm away from the cell wall of a plant or bacterium due to water loss from osmosis.
