What is one of the major roles of the phloem, opposed to xylem?

The phloem's primary role is in the transport of sugars and other organic nutrients produced during photosynthesis from the leaves to various parts of the plant, such as stems and roots. This process is crucial for the plant's growth and energy supply, as sugars serve as a primary energy source for metabolic activities.

In contrast, the xylem is primarily responsible for transporting water and dissolved minerals from the roots to the rest of the plant. While structural support is provided mainly by the xylem through its lignified cell walls, phloem does not contribute significantly to the structure. Therefore, when considering the distinct functions of these two vascular tissues, the phloem's role in transporting sugars makes it essential for nutrition and energy distribution within the plant.
