Detailed explanation-1: -Transpiration is defined as the process where plants absorb water through the roots and then give off water vapour through pores in their leaves (stomata). This process removes excess water, creates a suction pull to help in transport of water upwards, and cools down the plant.

Detailed explanation-2: -Transpiration serves to evaporatively cool plants, as the evaporating water carries away heat energy due to its large latent heat of vaporization of 2260 kJ per liter. More leaves (or spines, or other photosynthesizing organs) means a bigger surface area and more stomata for gaseous exchange.

Detailed explanation-3: -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.

Detailed explanation-4: -Transpiration is the process in which plants release the water inside it in the form of moisture or water vapor. Roots consume some amount of water from the soil and the rest evaporates in the atmosphere. Parts of plants such as stems, small pores on leaves, and flowers evaporate the water to the atmosphere.
