The function of phloem in plants is primarily to transport metabolic compounds, particularly the sugars produced during photosynthesis, from the leaves (where they are synthesized) to other parts of the plant that utilize these compounds for growth, energy, and storage. This process is essential for the plant's overall functioning, as it ensures that energy-rich compounds are delivered to areas of active growth or storage, such as roots, fruits, and developing leaves.

Phloem assists in the process of translocation, which is the movement of these organic nutrients throughout the plant. Unlike xylem, which transports water and minerals from the roots to the leaves, phloem works in the opposite direction, supporting the plant's energy needs and growth through the distribution of carbohydrates and other organic molecules. This role is crucial for the plant’s ability to optimize resource use, particularly in different environmental conditions or stages of development.
