transpiration
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.I
Evaporation. Water molecules have a cohesive property, so as water molecules closest to the stoma evaporate and diffuse through the stoma they will pull the water molecules from the xylem behind them. These water molecules will evaporate too and draw more water up.
Transpirationis a process similar to evaporation. Water is lost in the form of water vapour (H2O) through microscopic pores on the undersides of leaves called stoma (or plural stomata).The process is sometimes also known as evapo-transpiration.

On average, around 90-95% of the water a plant takes in through its roots is lost through transpiration. This process helps plants regulate their temperature and move nutrients through their system.
Water is lost through transpiration, a process where plants release water vapor through their leaves. This loss of water through transpiration is generally higher than the amount used for photosynthesis in most plants.
transpiration
From the leaves in the main by a process known as transpiration. Smaller quantities can be lost by the stem and roots. The loss of water through the stomata of the leaves makes way for new water from the roots which brings vital nutrients.
