  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, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain other vascular plants. It produces secondary xylem inwards, towards the pith, and secondary phloem outwards, towards the bark.

  3. Phloem - Wikipedia

    en.wikipedia.org/wiki/Phloem

    Phloem (/ ˈ f l oʊ. əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant.

  4. Plant stem - Wikipedia

    en.wikipedia.org/wiki/Plant_stem

    Most or all ground tissue may be lost in woody stems. Vascular tissue, consisting of xylem, phloem and cambium; provides long distance transport of water, minerals and metabolites (sugars, amino acids); whilst aiding structural support and growth. The arrangement of the vascular tissues varies widely among plant species. [8]

  5. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    Between the xylem and phloem is a meristem called the vascular cambium. This tissue divides off cells that will become additional xylem and phloem. This growth increases the girth of the plant, rather than its length. As long as the vascular cambium continues to produce new cells, the plant will continue to grow more stout. In trees and other ...

  6. Vascular bundle - Wikipedia

    en.wikipedia.org/wiki/Vascular_bundle

    A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. There is also a tissue between xylem and phloem, which is the cambium.

  7. Vascular plant - Wikipedia

    en.wikipedia.org/wiki/Vascular_plant

    Xylem is the water-conducting tissue, and the secondary xylem provides the raw material for the forest products industry. [25] Xylem and phloem tissues each play a part in the conduction processes within plants. Sugars are conveyed throughout the plant in the phloem; water and other nutrients pass through the xylem.

  8. 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 ...

  9. 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.
