  • Describe the different parts that make up the Polyp and what they do. (Tentacle, mouth, basal plate, etc.)[3]
  • Explain how nerve cells loosely connect Polyps to one another creating a nerve net between a colony of Polyps


Symbiotic relationship with zooxanthellae

  • Define symbiosis.
  • Explain how Polyps and Zooxzanthellae have a symbiotic relationship. (what each does for each other)[4]
  • Explain how through this relationship both are mutually benefited.
  • Explain how the relationship is also obligative. Meaning that, in most cases, neither can live without the other.

Stony Coral and Soft Coral Coral

  • Stony corals make a calcium carbonate skeleton, soft corals do not do this

Feeding

  • How Polyps are able to use their tentacles to pull in zooplankton and small fish to their mouths

Reproduction

  • Explain the process of reproduction
