  2. Mycorrhizal network - Wikipedia

    en.wikipedia.org/wiki/Mycorrhizal_network

    The mycorrhizal symbiosis between plants and fungi is fundamental to terrestrial ecosystems, with evolutionary origins before the colonization of land by plants. [17] In the mycorrhizal symbiosis, a plant and a fungus become physically linked to one another and establish an exchange of resources between one another.

  3. Root nodule - Wikipedia

    en.wikipedia.org/wiki/Root_nodule

    The root hairs curled in the direction of the application, demonstrating the action of a root hair attempting to curl around a bacterium. Even application on lateral roots caused curling. This demonstrated that it is the nod factor itself, not the bacterium that causes the stimulation of the curling.

    The first known species of rhizobia, Rhizobium leguminosarum, was identified in 1889, and all further species were initially placed in the Rhizobium genus.Most research has been done on crop and forage legumes such as clover, alfalfa, beans, peas, and soybeans; more research is being done on North American legumes.

    en.wikipedia.org/wiki/Root

    A true root system consists of a primary root and secondary roots (or lateral roots). the diffuse root system: the primary root is not dominant; the whole root system is fibrous and branches in all directions. Most common in monocots. The main function of the fibrous root is to anchor the plant.

  8. Aerenchyma - Wikipedia

    en.wikipedia.org/wiki/Aerenchyma

    Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

  9. 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.
