Final answer:
During a period of severe drought, the plant cell would shrink, causing the plant to wilt.
Step-by-step explanation:
Approximately two-thirds of the mass of a cell is water, and the water integrity is vital for maintaining the cell's structure and function. During a period of severe drought, the cell would eventually shrink, causing the plant to wilt. This is because the water content within the cell decreases, leading to a loss of turgor pressure and the plant's inability to maintain its shape and support its growth.
