The phloem in plants transports food, mainly sucrose, from the leaves where it is produced to all other parts of the plant, including roots, stems and fruits, supplying energy and materials necessary for growth, storage and development.

Phloem plays an important role in translocation. It transports prepared food, mainly sucrose, from the leaves (source) to storage organs, stems, roots, fruits, and growing regions (sink) through the process of active transport.
The phloem plays a vital role in the transport system of plants. It is responsible for translocation, the process of transporting prepared food, mainly sucrose, from the leaves (where photosynthesis occurs) to different parts of the plant. This transport occurs in both upward and downward directions to supply energy to growing regions such as roots, shoots, flowers, and fruits. Phloem consists of specialized cells like sieve tubes and companion cells that facilitate this movement with the help of energy in the form of ATP. Thus, phloem ensures proper distribution of nutrients, supporting growth, storage, and overall functioning of the plant.
