Porifera & Cnidarian
Across
- 1. a type of invertebrate animal that has a hollow, cylinder-shaped body and is a member of the phylum Cnidaria.
- 6. microscopic, whip-like appendages that help cells move through liquids
- 8. a genus of small, tube-shaped calcareous sponges belonging to the family Sycettidae,
- 9. small openings or pores in the body of an animal or in organs within the body.
- 10. the large, central cavity of a sponge
- 13. having both male and female reproductive organs in the same individual, or being hermaphroditic.
- 14. an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel.
- 17. a small, sharp-pointed, hard body that serves as a skeletal element in various invertebrates, such as sponges and corals:
- 18. a free-swimming larval form of many cnidarians, such as jellyfish, corals, and sea anemones.
- 19. anything that is associated with or occurs on the bottom of a body of water
- 21. a form of asexual reproduction where a new organism develops as a small outgrowth or "bud" from the body of a parent organism, eventually detaching to become a separate individual
Down
- 2. organisms that drift in water and are unable to swim against currents.
- 3. an animal or plant that has both male and female reproductive organs, structures, or tissue.
- 4. having distinct individuals that are either male or female, and each produces either male or female gametes.
- 5. a young animal that is very different from its adult form, and that goes through a distinct stage in its development before becoming an adult
- 7. a type of sponge or sponge larva with a simple canal system and a vase-like body shape
- 8. an organism that is permanently attached to a solid surface and is unable to move on its own
- 11. a type of sponge with a complex structure that includes a thick body wall and a highly branched canal system:
- 12. an animal (such as a clam or baleen whale) that obtains its food by filtering organic matter or minute organisms from a current of water that passes through some part of its system.
- 15. the free-swimming, bell-shaped body form of a cnidarian (like a jellyfish),
- 16. a protein that makes up the flexible fibers that form the skeleton of most sponges.
- 20. having the ability to contract or cause contraction
