A- The diagram illustrates the process of wilting, i.e., more water is lost hy transpiration.
The plant was subjected to high heat and light conditions that resulted in it losing more water than it can absorb from the soil. When the water evaporated is not replaced by water absorbed by the roots at the same rate, the tissue becomes flaccid and the leaves wilt.
