mantle

Examples of mantle in the following topics:

• Phylum Mollusca

  • Mollusks have a soft body and share several characteristics, including a muscular foot, a visceral mass of internal organs, and a mantle.
  • In spite of their tremendous diversity, however, they also share a few key characteristics, including a muscular foot, a visceral mass containing internal organs, and a mantle that may or may not secrete a shell of calcium carbonate .
  • It is the ventral-most organ, whereas the mantle is the limiting dorsal organ.
  • The mantle cavity develops independently of the coelomic cavity.
  • The mantle (also known as the pallium) is the dorsal epidermis in mollusks; shelled mollusks are specialized to secrete a chitinous and hard calcareous shell.

• Classification of Phylum Mollusca

  • They have a rudimentary mantle cavity and lack eyes, tentacles, and nephridia (excretory organs).
  • The mantle cavity encloses the ctenidia (singluar: ctenidium) as well as a pair of nephridia (singular: nephridium).
  • Ctenidia are enclosed in a large mantle cavity serviced by blood vessels, each with its own associated heart.
  • The mantle has siphonophores that facilitate exchange of water.
  • A pair of nephridia is present within the mantle cavity.

• Mycorrhizae: The Symbiotic Relationship between Fungi and Roots

  • Ectomycorrhizae form an extensive dense sheath around the roots, called a mantle .
  • Hyphae from the fungi extend from the mantle into the soil, which increases the surface area for water and mineral absorption.
  • Ectomycorrhizae form sheaths, called a mantle, around the roots of plants, as shown in this image.

• Mutualistic Relationships with Fungi and Fungivores

  • Ectomycorrhizae ("outside" mycorrhiza) depend on fungi enveloping the roots in a sheath (called a mantle) and a Hartig net of hyphae that extends into the roots between cells .
