    Study Notes

    Five Kingdom Classification System

    • The classification system consists of five kingdoms: Monera, Protista, Fungia, Plantae, and Animalia.

    Kingdom Protista

    • The kingdom Protista includes eukaryotic organisms that do not fit into any of the other four kingdoms.
    • Protists can be classified into three categories based on their mode of nutrition:
      • Animal-like protists that consume other organisms.
      • Plant-like protists that produce their own food through photosynthesis.
      • Fungus-like protists that obtain food by external digestion, either as decomposers or parasites.

    Sponges

    • The body of a sponge is a collection of a few different types of cells loosely arranged in a gelatinous matrix called a mesohyl.
    • The mesohyl is the connective tissue of a sponge body and is supported by skeletal elements.
    • The skeletal elements of sponges are variable and important in taxonomy.

    Canal Systems in Sponges

    • There are three main types of canal systems in sponges: Asconoid, Syconoid, and Leuconoid.
    • Asconoid sponges have canals that run straight through the sponge body.
    • Syconoid sponges have canals that are branched and do not allow water to flow straight through to the spongocoel.
    • Leuconoid sponges have a more complicated canal system with longer and more branched canals.
