Anchorage meaning in biology cnidaria. Like sponges and ctenophores, cnidarians have two main layers of cells that sandwich a middle layer of jelly-like material, which is called the mesoglea in Understanding the meaning of anchorage in biology involves exploring how different organisms achieve attachment, the molecular and structural components involved, and the functional Anchorage strength is the force at which the roots break or the whole plant, including most of its root system, is dislodged from the sediment. It is grounded on an evolutionary basis and includes exciting features that highlight Members of the Phylum Cnidaria are characterized by the possession of cnidae, those curious, everting, intracellular organelles that have both startled and in trigued humans for thousands Definition Mesoglea is a gelatinous, non-cellular layer found between the two main tissue layers in animals of the Phylum Cnidaria, primarily in jellyfish, corals, and sea anemones.
