Detailed explanation-1: -Transpiration helps in the conduction of water and minerals to different parts of the plants. Due to the continuous elimination of water from the plant body, there is a balance of water maintained within the plant. It maintains osmosis and keeps the cells rigid.

Detailed explanation-2: -Transpiration also provides the driving force for transport of water and nutrients from roots to shoots. Consequently, transpiration processes affect the yield and survival of agricultural species, and impact on the global carbon and hydrological cycles.

Detailed explanation-3: -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-4: -Cools the surface of the leaves. Helps in growth and development. It controls the temperature of the plants. Allows the movement of minerals from the soil to different parts of the plant.

Detailed explanation-5: -Maintaining plant structure – transpiration helps in maintaining the turgidity in plants since young plants that do not have woody stems need water for their structural support. Ensuring the cooling of plant – the loss of water in the form of water vapour from plants helps the plant to cool down during hot days.
