  2. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. 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 ...

  3. Vascular plant - Wikipedia

    en.wikipedia.org/wiki/Vascular_plant

    Botanists define vascular plants by three primary characteristics: Vascular plants have vascular tissues which distribute resources through the plant. Two kinds of vascular tissue occur in plants: xylem and phloem. Phloem and xylem are closely associated with one another and are typically located immediately adjacent to each other in the plant.

  4. Stele (biology) - Wikipedia

    en.wikipedia.org/wiki/Stele_(biology)

    In a vascular plant, the stele is the central part of the root or stem [1] containing the tissues derived from the procambium. These include vascular tissue , in some cases ground tissue ( pith ) and a pericycle , which, if present, defines the outermost boundary of the stele.

  5. Tissue (biology) - Wikipedia

    en.wikipedia.org/wiki/Tissue_(biology)

    In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis – Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue – The primary components of vascular tissue are the xylem and phloem. These transport fluids and ...

  6. 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. This transport process is called translocation. [2]

  7. 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.

  8. 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.

  9. Polysporangiophyte - Wikipedia

    en.wikipedia.org/wiki/Polysporangiophyte

    According to the cladogram, the genus Rhynia illustrates two steps in the evolution of modern vascular plants. Plants have vascular tissue, albeit significantly simpler than modern vascular plants. Their gametophytes are distinctly smaller than their sporophytes (but have vascular tissue, unlike almost all modern vascular plants). [28]
