Phloem science
WebbThere are two major types of transport vessels within the plants vascular system: xylem and phloem (pronounced zy-lem and flo-em). Xylem tubes carry water and minerals obtained from the roots of the plant to the tissues above ground. Phloem tissue transport the sugars produced in the leaves to the tissues in the rest of the plant.
