Examples of rhizoid in the following topics:

  • Mosses

    • Mosses are bryophytes that live in many environments and are characterized by their short flat leaves, root-like rhizoids, and peristomes.
    • In the tundra, the mosses' shallow rhizoids allow them to fasten to a substrate without penetrating the frozen soil.
    • Additionally, mosses are anchored to the substrate, whether it is soil, rock, or roof tiles, by multicellular rhizoids.
    • Rhizoids form at the base of the gametophore.
  • Bryophytes

    • In a bryophyte, all the conspicuous vegetative organs, including the photosynthetic leaf-like structures, the thallus, stem, and the rhizoid that anchors the plant to its substrate, belong to the haploid organism, or gametophyte.
  • Evolution of Land Plants

    • The area inside the circle contains bulbous underground stems called corms and root-like structures called rhizoids.
  • Ferns and Other Seedless Vascular Plants

    • Those that land on a suitable substrate germinate and form a heart-shaped gametophyte, which is attached to the ground by thin filamentous rhizoids.
