Phloem transport is bidirectional, since the requirement of food in a plant is both ways(roots and shoots both), so food is transported downwards as well as upwards and hence this is an active process consuming energy.
One thing that separates phloem tissue from xylem tissue is that phloem has a two-way flow of organic compounds and water, while xylem mainly has a one-way flow. Phloem tissue brings carbohydrates to the stems, leaves, and the roots, rather than just the stems and leaves from the roots.
