  2. Plant intelligence - Wikipedia

    en.wikipedia.org/wiki/Plant_intelligence

    Plant intelligence (also known as plant cognition or plant neurobiology) is a field of plant biology which aims to understand how plants process the information they obtain from their environment. [ 2 ] [ 3 ] [ 4 ] Plant neurobiological researchers claim that plants possess abilities associated with cognition including anticipation, decision ...

  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. Rhynia - Wikipedia

    en.wikipedia.org/wiki/Rhynia

    Rhynia gwynne-vaughanii was the sporophyte [2] generation of a vascular, axial, free-sporing diplohaplontic embryophytic land plant of the Early Devonian that had anatomical features more advanced than those of the bryophytes. Rhynia gwynne-vaughanii was a member of a sister group to all other eutracheophytes, including modern vascular plants.

  5. Stele (biology) - Wikipedia

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

    Among living plants, this type of stele is found only in the stems of ferns. Most seed plant stems possess a vascular arrangement which has been interpreted as a derived siphonostele, and is called a eustele – in this arrangement, the primary vascular tissue consists of vascular bundles, usually in one or two rings around the pith. [12]

  6. Kubitzki system - Wikipedia

    en.wikipedia.org/wiki/Kubitzki_system

    The survey, in the form of an encyclopedia, is important as a comprehensive, multivolume treatment of the vascular plants, with keys to and descriptions of all families and genera, mostly by specialists in those groups. The Kubitzki system served as the basis for classification in Mabberley's Plant-Book, a dictionary of the vascular plants. [2]

  7. Lycophyte - Wikipedia

    en.wikipedia.org/wiki/Lycophyte

    They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the Silurian (ca. 425 million years ago). [ 2 ] [ 3 ] Lycophytes were some of the dominating plant species of the Carboniferous period, and included the tree-like Lepidodendrales , some of which grew over 40 metres ...

  9. Tracheid - Wikipedia

    en.wikipedia.org/wiki/Tracheid

    Tracheids were the main conductive cells found in early vascular plants. In the first 140-150 million years of vascular plant evolution, tracheids were the only type of conductive cells found in fossils of plant xylem tissues. [5] Ancestral tracheids did not contribute significantly to structural support, as can be seen in extant ferns. [6]
