  2. Vascular cambium - Wikipedia

    en.wikipedia.org/wiki/Vascular_cambium

    The vascular cambium is the main growth tissue in the stems and roots of many plants, ... Other names for the vascular cambium are the main cambium, wood cambium, ...

  3. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant.

  4. Bark (botany) - Wikipedia

    en.wikipedia.org/wiki/Bark_(botany)

    Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. [1] It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm.

  5. Cambium - Wikipedia

    en.wikipedia.org/wiki/Cambium

    A cambium (pl.: cambiums or cambia), in plants, is a tissue layer that provides partially undifferentiated cells for plant growth. It is found in the area between xylem and phloem . A cambium can also be defined as a cellular plant tissue from which phloem, xylem, or cork grows by division, resulting (in woody plants) in secondary thickening.

  6. Calamites - Wikipedia

    en.wikipedia.org/wiki/Calamites

    Their trunks produced secondary xylem, meaning they were made of wood. The vascular cambium of Calamites was unifacial, producing secondary xylem towards the stem center, but not secondary phloem. The stems of modern horsetails are typically hollow or contain numerous elongated air-filled sacs.

  7. Woody plant - Wikipedia

    en.wikipedia.org/wiki/Woody_plant

    Xylem is a vascular tissue which moves water and nutrients from the roots to the leaves. Most woody plants form new layers of woody tissue each year, and so increase their stem diameter from year to year, with new wood deposited on the inner side of a vascular cambium layer located immediately beneath the

  9. Tree - Wikipedia

    en.wikipedia.org/wiki/Tree

    In trees and other plants that develop wood, the vascular cambium allows the expansion of vascular tissue that produces woody growth. Because this growth ruptures the epidermis of the stem, woody plants also have a cork cambium that develops among the phloem.
