Concept:Wilting is the drooping or loss of rigidity in a plant caused by a decrease in water content and turgor pressure.
Explanation:Initially, Plant A was firm and turgid because its cells had a high turgor pressure.
After seven hours, Plant A looked exactly like Plant B, which appears limp, drooping, and less firm.
This change in appearance shows that Plant A lost a significant amount of water.
When water leaves the cells, turgor pressure falls, and the leaves and stem lose their support.
In this condition, a plant is described as wilted.
Transpiration helps remove water from the plant, but the visible drooping response seen here is wilting.
