WebbThe phloem and xylem is separated by meristematic tissue known as cambium, which is responsible for secondary thickening. Xylem has lignified cell walls which helps it fulfil its two important roles, namely; strengthening and supporting the stem, and transporting water and minerals from the root system to the leaves. WebbPhloem is one of the two tissues that make up the plant's long-distance transport system, the other being xylem.
