Define Xylem, Phloem and Cambium.
Define Xylem, Phloem and Cambium. Xylem: Xylem is a series of tubes that moves water and minerals. Xylem tissue conducts in only one direction-up from the plant roots to the leaves. Phloem: Phloem moves sugars that are made in the plant's leaves to other parts of the plant. It flows both up and down in a plant. Phloem tissue is a two- way transport route. Cambium: The xylem and phloem layers in a plant stem are separated by a layer called the cambium. Xylem and phloem cells are produced in the cambium.
