What are the the functions of Phloem and why it is important for the plant? 

Phloem is one of the types of vascular tissues present in plants that transports various inorganic nutrients and sugars such as sucrose to different parts of the plant body. The main function of phloem is to transport nutrients and sap (a water-based solution rich in sugar content) from one part of the plant to another which is essential for the growth and maintenance of the plant.
