WebbProcess of phloem transport. Products of photosynthesis (primarily sugars) move through phloem from leaves to growing tissues and storage organs. The areas of growth may be newly formed leaves above the photosynthesizing leaves, growing fruits, or pollinated flowers. Storage organs are found in roots, bulbs, tubers, and stems. WebbThe phloem conducts these nutrients, which are made in the leaves, to all the cells in the plant so that the plant can have the materials it needs to grow and reproduce.
