  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. 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.

  4. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    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 . In leaves , the vascular bundles are located among the spongy mesophyll .

  5. Meristem - Wikipedia

    en.wikipedia.org/wiki/Meristem

    Lateral meristems, the form of secondary plant growth, add growth to the plants in their diameter. This is primarily observed in perennial dicots that survive from year to year. There are two types of lateral meristems: vascular cambium and cork cambium. In vascular cambium, the primary phloem and xylem are produced by the apical meristem.

  6. 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 ]

  7. Substrate (aquarium) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(aquarium)

    For freshwater aquaria, gravel is the most common substrate. To prevent damage to fish, gravel should not be sharp. Aquarium gravel can be as coarse as pea-sized or as fine as 1–2 mm. [1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]

  8. Cork (material) - Wikipedia

    en.wikipedia.org/wiki/Cork_(material)

    Harvesting of cork from the forests of Algeria, 1930. Cork is a natural material used by humans for over 5,000 years. It is a material whose applications have been known since antiquity, especially in floating devices and as stopper for beverages, mainly wine, whose market, from the early twentieth century, had a massive expansion, particularly due to the development of several cork-based ...

  9. Bark (botany) - Wikipedia

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

    A limited number of cell layers may form interior to the cork cambium, called the phelloderm. As the stem grows, the cork cambium produces new layers of cork which are impermeable to gases and water and the cells outside the periderm, namely the epidermis, cortex and older secondary phloem die. [32]
