Detailed explanation-1: -On a hot, dry day (or after several days with no rain or watering), transpiration causes more water to be lost than is coming in, and the water balance within the plant can get thrown off. The dehydrated collapsing cells in the leaves and stems can no longer remain erect, and the plant begins to wilt.
Detailed explanation-2: -When the soil of a plant runs too low of available water, the water chains in the xylem become thinner and thinner due to less water. Effectively, the plant is losing water faster than it is absorbing it. When this happens, the plant loses its turgidity and begins to wilt.
Detailed explanation-3: -In such cases, the rate of transpiration during midday exceeds the rate of absorption of water by the roots. The cells, therefore, lose turgidity. So, excessive transpiration results in wilting of the leaves.
Detailed explanation-4: -When plants lose excess water, the rate of absorption increases and wilting takes place. When wilting occurs, the cells of the plants lose water and become dry. When the conditions are dry and hot in summer, the rate of water evaporation is rapid.
