Question

causes cell to wilt?

Answer 1

There are many reasons that a plant cell wilts. Lack of water in the plant's cells (lower turgidity) reduces its ability to remain rigid or erect. Other reasons are diseases, bacteria or fungi that block or reduce the plants ability to transfer water through the body of the plant. Lack of rainfall or over-watering will saturate the soil and not allow the roots to receive oxygen. Another reason for wilt is high salinity which will draw water from the plant and shrink the cells.
