Porifera And Coelenterata Test - Quiz

  • 2. 

    The Phylum Coelenerata is also called...

    Explanation
    The correct answer is Cnidaria. The phylum Coelenterata is an outdated term that is no longer used in modern classification systems. However, it was previously used to refer to the phylum Cnidaria, which includes animals like jellyfish, corals, and sea anemones. Cnidaria is characterized by the presence of specialized cells called cnidocytes, which contain stinging structures called nematocysts. These animals have radial symmetry and a simple body plan, with a central cavity called the coelenteron.

  • 3. 

    Organisms classified in the Phylum Porifera...

    • Are asymmetrical

    • Have bilateral symmetry

    • Have radial symmetry

    Correct Answer
    A. Are asymmetrical
    Explanation
    Organisms classified in the Phylum Porifera are asymmetrical. This means that their bodies do not have any definite shape or symmetry. Porifera, commonly known as sponges, have a simple body structure with numerous pores and canals. They lack any specialized tissues or organs, and their body shape can vary greatly. This lack of symmetry allows them to filter and circulate water efficiently through their bodies, enabling them to obtain nutrients and oxygen.

    Rate this question:

  • 6. 

    The word "porifera" means what?

    Correct Answer
    pore bearing
    Pore bearing
    pore-bearing
    Pore-bearing
    Explanation
    The word "porifera" is derived from Latin roots, where "por" means pore and "fera" means bearing. Therefore, "porifera" means "pore bearing" or "bearing pores". The term is used to describe a phylum of animals that includes sponges, which have numerous pores on their bodies for water circulation and feeding.

    Rate this question:

  • 8. 

    There are three Porifera classes. Name them in alphabetical order with a capitilized first letter for every word and semicolon between. Name in parentheses what it is made out of and an example of it. Ex: (not real) If Lopinia was a class and organisms in that class were made out of Co3O2 otherwise known as burgers and an example of Lopinia was a cheeseburger, I would write: Lopinia (Co302 - burgers) cheeseburger                            Note: if there is no scientific name for it don't say it

    Correct Answer
    Calcarea (CaCO3 - Lime) Leucosolenia; Hexactinellida (Silicon - Glass) Eupectela; Demospongiae (Spongin) Calcaria
    Explanation
    The three classes of Porifera, listed in alphabetical order, are Calcarea, Demospongiae, and Hexactinellida. Calcarea is made out of CaCO3, also known as Lime, and an example of this class is Leucosolenia. Hexactinellida is made out of Silicon, which forms Glass, and an example of this class is Eupectela. Demospongiae is made out of a substance called Spongin, and an example of this class is Calcaria.

    Rate this question:

  • 9. 

    Organisms classified in the Phylum Porifera evolved about how many million years ago?

    Correct Answer
    700
    700 million years ago
    About 700
    About 700 million years ago
    about 700 million years ago
    about 700
    Explanation
    Organisms classified in the Phylum Porifera evolved about 700 million years ago.

    Rate this question:

  • 10. 

    There are about  ___________  species of Coelenterata.

    Correct Answer
    9,000
    9000
    nine-thousand
    Nine-thousand
    Nine thousand
    nine thousand
    Explanation
    Coelenterata is a phylum that includes various species of animals such as jellyfish, sea anemones, and coral. The question is asking for the number of species in this phylum. The correct answer is "9,000" or "9000" which represents the approximate number of species within the Coelenterata phylum.

    Rate this question:

  • 11. 

    The word Coelenterata or Cnidaria means a...

    Correct Answer
    hollow gut
    Hollow gut
    Explanation
    The term "Coelenterata" or "Cnidaria" refers to a group of animals that have a hollow gut. This means that their digestive system consists of a central cavity that acts as both a mouth and an anus. The hollow gut allows for the efficient digestion and absorption of nutrients.

  • 12. 

    Specialized Porifera cells can either... (no caps with comma between words and add "or" before last word)

    Correct Answer
    store food, produce gametes, or produce spicules
    store food, produce spicules, or produce gametes
    produce gametes, store food, or produce spicules
    produce gametes, produce spicules, or store food
    produce spicules, store food, or produce gametes
    produce spicules, produce gametes, or store food
  • 13. 

    Porifera classes are grouped by

    Correct Answer
    what the spicule is made of
    What the spicule is made of
    what the spicule is made out of
    What the spicule is made out of
    Explanation
    The correct answer for this question is that Porifera classes are grouped by what the spicule is made of. Spicules are tiny, needle-like structures found in the body of sponges, and they can be made of different materials such as calcium carbonate or silica. The composition of the spicule is used as a characteristic feature to classify and group different classes of Porifera.

    Rate this question:

  • 14. 

    Organisms classified in the Phylum Porifera are... (think habitat then state in parenthases where they are mostly found then where they are also found; no caps)

    Correct Answer
    aquatic (marine and freshwater)
    Explanation
    Organisms classified in the Phylum Porifera are aquatic, meaning they live in water. They can be found in both marine environments, such as oceans and seas, as well as freshwater environments, including lakes and rivers.

    Rate this question:

  • 15. 

    Organisms classified in the Phylum Porifera are always sessile. (sessile=do not move)

    • True

    • False

    Correct Answer
    A. False
    Explanation
    They are sessile most of the time as some are motile, meaning they do move.

    Rate this question:

  • 16. 

    Spicules are like...

    Correct Answer
    bones for sponges
    Bones for sponges
    Explanation
    Spicules are needle-like structures made of calcium carbonate or silica that provide structural support to sponges, similar to how bones provide support to the human body. These spicules help maintain the shape and rigidity of the sponge's body, allowing it to withstand water currents and predators. Therefore, comparing spicules to bones is an accurate analogy to understand their function in sponges.

  • 17. 

    There are three types of porifera cell types. List them with capitilized letters and semicolons between in order of outside cells, inside cells, and specialized cells.

    Correct Answer
    Pinacocytes; Choanocytes; Amoebocytes
    Explanation
    The three types of cell types in porifera are pinacocytes, choanocytes, and amoebocytes. Pinacocytes are the outermost cells that form a protective layer on the surface of the sponge. Choanocytes are found inside the sponge and have a collar-like structure that helps in generating water currents and capturing food particles. Amoebocytes are specialized cells that are responsible for various functions such as digestion, transportation of nutrients, and production of skeletal elements.

    Rate this question:

  • 18. 

    Organisms classified in the Phylum Porifera have no... (three things; no caps)

    Correct Answer
    tissues, organs, and distinct body design
    tissues, organs, or distinct body design
    tissues; organs; distinct body design
    tissues, organs, distinct body design
    Explanation
    Organisms classified in the Phylum Porifera have no tissues, organs, or distinct body design. Porifera, also known as sponges, are the simplest multicellular animals and lack specialized tissues and organs. They have a simple body structure with specialized cells that perform different functions but do not form true tissues. They also lack distinct body design or symmetry, unlike other higher animal groups.
