Jellyfish and Corals

3. 1 - $200
Phylum Porifera consist of what animals?
Sponges

4. 1 - $300 Phylum Echinodermata consists of what animals?
Sea stars, sea lillies, brittle stars

5. 1 - $400 Phylum Arthopoda consists of what animals?
Insects, arachnids, myriapods, and crustaceans

6. 1 - $500 Name the three “worm” phyla and the common name for each.
Playhelminthes – flatworms
Nematoda – roundworms
Annelida – segmented worms

7. 2 - $100 What is the difference between a protostome and deuterostome?
Protostome – blastula becomes mouth
Deuterostome – blastula becomes anus

8. 2 - $200
What are animals called that only have the ectoderm and endoderm?
What animals called that have all three germ layers during development?
Diploblast
Triploblast

9. 2 - $300
What are organisms called who have body cavities not completely lined by tissues derived from the mesoderm?
Pseudocoelomates

10. 2 - $400
What are organisms called that have a body cavity completely lined by tissues derived from the mesoderm?
What are organisms called that have a body cavity that is not at all lined by tissues derived from the mesoderm?
Coelomates
Acoelomates

11. 2 - $500
What are the three germ layers and what does each germ layer form?
Ectoderm – forms the outer covering and nervous tissue of an organism
Mesoderm – forms muscles and most other organs
Endoderm – forms lining of the digestive tract

12. 3 - $100 What phylum does this insect belong to? Phylum: Arthropoda
Order: Hymenoptera

13. 3 - $200
What order does this insect belong to?
Orthoptera

14. 3 - $300 What phylum does this organism belong to?
Phylum Platyhelminthes
Class Cestoda
Parasitic flatworm, you can tell it’s a cestode because it has scolex

15. 3 - $400
What kind of animal is this? Where is the corona and what is it’s function?
Rotifer. The corona is located at the top (greenish), the cilia on it move/beat and form a water current which allows them to catch food

16. 3 - $500
This photo shows the two different body forms of cnidarians. What are the names of these two body forms?
Polyp (left) and Medusa (right)

17. 4 - $100
Rotifers – complete or incomplete digestion?
Complete

18. 4 - $200
What is a hermaphrodite? Serial hermaphrodite? Name a phylum that has species that exhibit this behavior.
Hermaphrodite – can produce both sperm and eggs
Serial hermaphrodite – at any one time, an individual can be either male or female
Example: sponges (Porifera)

19. 4 - $300
Do jellyfish and corals have internal or external fertilization?
External. They release their sperm and eggs into the water. They work together (do it in unison) and release their sperm and eggs at the same time.

20. 4 - $400 Do earthworms have a complete or incomplete digestive system?

21. 4 - $500 Explain Cnidarian digestion.
Tentacles push food through mouth into gastrovascular cavity. The cavity has an entrance (the mouth) but no exit (anus). It is an incomplete digestive system. Digestion is a combination of intracellular and extracellular. Can’t digest everything, some is regurgitated through the mouth, the rest is absorbed.

22. 5 - $100
True or False – sponge sperm is sessile, just like adult sponges.
False! They have a flagellated motile larvel form.

23. 5 - $200 True or False – Cnidarians are herbivores.
False. They are carnivores.

24. 5 - $300
True or False – many flatworm species are parasites.
True

25. 5 - $400 True or False – Playhelminthes are coelomates.
False. They are acoelomates, meaning that they do not have a body cavity.

26. 5 - $500
True or False – Annelids are coelomates and have an incomplete digestive system.
False. They ARE coelomates, but they have a complete digestive system.

27. Final Jeopardy What are the characteristics of animals?
Multicellular, chemoorganoheterotrophic eukaryotes
Typically obtain nutrition through ingestion
Lack cell walls
They are motile – at least during some stages of their life cycle
All animals (except sponges) have nerve cells and muscle cells
