Transpiration

-
This loss of water in plants takes place through the process of transpiration in which the water evaporates in the atmosphere through the stomata present on the leaves.
Stomata are tiny pores present on the leaves that allow the movement of gases and water through them.
Transpiration results in absorption of water: As the water from the leaves evaporates, it generates a suction pull in the plants that bring the water from the roots upwards.
Transpiration helps in cooling down the plants: As the water evaporates, it utilizes the heat of the pant and results in cooling of the internal temperature of the plant.
Xylem – It is a vascular tissue that is responsible for transporting nutrients and water in the plants. The root cells absorb water and minerals and transport it to xylem. Xylem carries it to other parts unidirectionally without usage of energy.
Phloem – It is a vascular tissue that transports the food produced by the leaves (source) to all parts of the plant (sink) . This flow is bidirectional and utilizes energy. This is known as translocation.
