  2. Cork cambium - Wikipedia

    en.wikipedia.org/wiki/Cork_cambium

    Cork cambium (pl.: cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis. It is one of the many layers of bark , between the cork and primary phloem . The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems .

  3. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    Because this growth ruptures the epidermis of the stem, woody plants also have a cork cambium that develops among the phloem. The cork cambium gives rise to thickened cork cells to protect the surface of the plant and reduce water loss. Both the production of wood and the production of cork are forms of secondary growth.

  4. Secondary growth - Wikipedia

    en.wikipedia.org/wiki/Secondary_growth

    Secondary growth thickens the stem and roots, typically making them woody.Obstructions such as this metal post and stubs of limbs can be engulfed. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems ...

  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. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    The vascular cambium cells divide to produce secondary xylem to the inside and secondary phloem to the outside. As the stem increases in diameter due to production of secondary xylem and secondary phloem, the cortex and epidermis are eventually destroyed. Before the cortex is destroyed, a cork cambium develops there.

  7. Complementary cells - Wikipedia

    en.wikipedia.org/wiki/Complementary_cells

    Complementary cells are a mass of cells in plants, formed from the cork cambium at the position of the lenticels. It is a group of loosely arranged cells that aid in gaseous exchange through cork . [ 1 ]

  9. Plant stem cell - Wikipedia

    en.wikipedia.org/wiki/Plant_stem_cell

    Traditionally, plant stem cells were thought to only exist in SAM and RAM and studies were conducted based on this assumption. However, recent studies have indicated that (pro)cambium also serves as a niche for plant stem cells: "Procambium cells fulfill the criteria for being stem cells since they have the capacity for long-term self renewal and being able to differentiate into one or more ...
