    Runner – an above-ground stem, usually rooting and producing new plants at the nodes. Sapwood – Scandent – a stem that climbs. Spine – an adapted leaf that is usually hard and sharp and is used for protection, and occasionally shading, of the plant; Stem – vascular tissue that provides support for the plant,

  3. Aerial root - Wikipedia

    en.wikipedia.org/wiki/Aerial_root

    Aerial roots are roots growing above the ground. They are often adventitious , i.e. formed from nonroot tissue. They are found in diverse plant species, including epiphytes such as orchids ( Orchidaceae ), tropical coastal swamp trees such as mangroves , banyan figs ( Ficus subg.

  4. Stratification (vegetation) - Wikipedia

    en.wikipedia.org/wiki/Stratification_(vegetation)

    The plants of a layer, especially with regard to their way of life and correspondingly similar root distribution interact closely and compete strongly for space, light, water and nutrients. The stratification of a plant community is the result of long selection and adaptation processes. Through the formation of different layers a given habitat ...

  5. Root - Wikipedia

    en.wikipedia.org/wiki/Root

    In some Epiphytes – plants living above the surface on other plants, aerial roots serve for reaching to water sources or reaching the surface, and then functioning as regular surface roots. [31] Canopy roots/arboreal roots: roots that form when tree branches support mats of epiphytes and detritus, which hold water and nutrients in the canopy ...

  6. Phreatophyte - Wikipedia

    en.wikipedia.org/wiki/Phreatophyte

    These plants have very deep roots that are able to reach the water table. Phreatophytes are not only characteristic of arid or desert zones, but also of wetlands, floodplains, depressions that hold water and estuaries. In the wetlands, ecological classification does not provide a special classification, since in this case, most of the plants in ...

    Boscia albitrunca, commonly known as the shepherd tree or shepherd's tree (Afrikaans: Witgat, Sotho: Mohlôpi, Tswana: Motlôpi, Venda: Muvhombwe, Xhosa: Umgqomogqomo, Zulu: Umvithi), is a protected species of South African tree in the caper family. [1] It is known for having the deepest known root structure of any plant at: -68 metres (223 ft ...

  8. Woody plant - Wikipedia

    en.wikipedia.org/wiki/Woody_plant

    The main stem, larger branches, and roots of these plants are usually covered by a layer of bark. Wood is a structural tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants .

  9. Plant morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_morphology

    The detailed study of reproductive structures in plants led to the discovery of the alternation of generations, found in all plants and most algae, by the German botanist Wilhelm Hofmeister. This discovery is one of the most important made in all of plant morphology, since it provides a common basis for understanding the life cycle of all plants.
