Detailed explanation-1: -Transpiration: When the water becomes excess for the plant body, the plants need to get rid of the extra water. Transpiration is the release of water from the stomatal openings of the leaves through the evaporation process. Excess water in plants is lost in the water vapor form.

Detailed explanation-2: -Stomata – Guard cells surrounds the stomata causing a doorway effect, which could be increasing (swollen) or decreasing (shrunken) in size. When the guard cells are swollen, stomata is sealed causing less water loss through transpiration.

Detailed explanation-3: -Transpiration is the process by which plants get rid of excess water through the stomata. The excess water is lost in the form of vapours by transpiration.

Detailed explanation-4: -Stomata respond to hydraulic perturbations in plant created by water evaporation and subsequent loss. In rainy season, stomata remain open even at night but in summer they either remain close or partially open to conserve water.
