What is tranpiration???

Transpiration is process just like EVAPORATION actually this is a process in which water from the leaves gets evaporated

Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants. Stoma are "pores" and are generally located on the underside of the leaves of plants.

Water accumulating in the leaves of the plants is lost as water vapor through the process of transpiration, this is similar to the process of sweating in animals.

Transpiration accomplishes two things, it does cool the leaves slightly through evaporative cooling, it also causes what is referred to as "evaporative draw" or "evaporative suction", this causes a slight low pressure in the leaves where the water is evaporating from, this provides a slight suction force assisting with water being drawn up the stem of the plant

Transpiration is the process by which plants loose water through the stomata present in their leaves. It helps in conduction of minerals absorbed by the root to the rest of plant.

Respiration is the process in which the food is broken down to release energy either in presence of oxygen (aerobic respiration) or in the absence of oxygen (anaerobic).
