  2. Root - Wikipedia

    en.wikipedia.org/wiki/Root

    The correct environment of air, mineral nutrients and water directs plant roots to grow in any direction to meet the plant's needs. Roots will shy or shrink away from dry [22] or other poor soil conditions. Gravitropism directs roots to grow downward at germination, the growth mechanism of plants that also causes the shoot to grow upward. [23]

  3. Dicentra - Wikipedia

    en.wikipedia.org/wiki/Dicentra

    Dicentra (Greek dís "twice", kéntron "spur"), [3] known collectively as the bleeding-hearts, is a genus containing eight species of herbaceous flowering perennial plants with unique, "heart"-shaped flowers and finely divided foliage. The species are, primarily, native to North America, although several are found in temperate East Asia.

  4. Abacá - Wikipedia

    en.wikipedia.org/wiki/Abacá

    The plant grows to 13–22 feet (4.0–6.7 m), and averages about 12 feet (3.7 m). The plant has great economic importance, being harvested for its fiber extracted from the leaf-stems. [4] [5] [6] The lustrous fiber is traditionally hand-loomed into various indigenous textiles (abaca cloth or medriñaque) in the Philippines.

  5. Root vegetable - Wikipedia

    en.wikipedia.org/wiki/Root_vegetable

    Root vegetables are underground plant parts eaten by humans or animals as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs , corms , rhizomes , and stem tubers .

  6. Sassafras - Wikipedia

    en.wikipedia.org/wiki/Sassafras

    The species are unusual in having three distinct leaf patterns on the same plant: unlobed oval, bilobed (mitten-shaped), and trilobed (three-pronged); the leaves are hardly ever five-lobed. [6] Three-lobed leaves are more common in Sassafras tzumu and S. randaiense than in their North American counterparts, although three-lobed leaves often ...

  7. Grafting - Wikipedia

    en.wikipedia.org/wiki/Grafting

    Grafting or graftage [1] is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion (/ ˈ s aɪ ə n /) while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together.

  8. Endophyte - Wikipedia

    en.wikipedia.org/wiki/Endophyte

    There is evidence that plants and endophytes engage in communication with each other that can aid symbiosis. For example, plant chemical signals have been shown to activate gene expression in endophytes. One example of this plant-endosymbiont interaction occurs between dicotyledonous plants in the Convolvulaceae and clavicipitaceous fungi.

  9. Root hair - Wikipedia

    en.wikipedia.org/wiki/Root_hair

    Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient. Root hairs are also important for nutrient uptake as they are main interface between plants and mycorrhizal fungi.
