  1. Symbiotic Relationships Lindsey Suttle, Mehran Hazeer, and Farvah Khaja

  2. Symbiosis • Means “living together” • Symbiont: smaller participant • Host There are not 3 definite categories of symbiotic relationships, some relationships overlap

  3. Three types of Symbiotic relationships: • Mutualism: +/+ • Commensalism: +/0 • Parasitism: +/- Mutualism: the honey bee and the flower, the bee gets nectar and the flower gets pollinated Commensalism: the clown fish and the sea anemone, the clown fish gets protection and a home, the sea anemone doesn’t benefit or detriment Parasitism: the mosquito and humans, the mosquito gets protein allowing her to lye her eggs and the human gets itchy bumps and possibly malaria, or other diseases

  5. Zooxanthellae • Single-celled plants • Part of dinoflagellates • Mutualism with corals • Protection, compounds needed for photosynthesis • Give food, products of photosynthesis, calcium for reef making • Bleaching when environmental stress adversely affects mutually beneficial relationship Zooxanthellae in a polyp coral

  6. Plasmodium • Protozoan parasite • Causes malaria • 300 million are infected in the tropics and 2 million die from the disease • Evasive • Hides from immunes system • Liver and blood cells • Continually changes “face” • Vaccines Plasmodium in red blood cells

  7. Life Cycle of Plasmodium

  8. TIC TAC TOE GAME!  1. Which type of symbiosis happens when one organism benefits and the other organism is hurt? 2. Which type of symbiosis occurs when both organisms benefit? 3. What is it called when one organism benefits and the other has no gain nor loss. 4. What is the parasite for malaria? 5. What organ cells does the plasmodium mainly invade?

  9. Tic Tac Toe continued… What type of symbiosis is shown: 6. 7.

  10. Game Continued… 8. What type of organism is zooxanthellae? 9. What is the smaller participant of symbiosis? 10. How does Zooxanthellae benefit from its relationship with coral?(give 2 benefits) 11. How does Coral benefit from from its relationship from Zooxanthellae?(give two benefits) 12. What are two causes of bleaching? 13. What cells do plasmodium hide in?(both)?

  11. Continued… 14. In the life cycle of a plasmodium, what does the liver cell release? 15. What are the two hosts in a plasmodium's life cycle? 16. Why does coral lose its color when under stress? 17. What is the non-symbiont of a relationship? 18. What are the parts of plasmodium that infect the liver? 19. In what area are there over 300 million people infected with malaria? 20. True/False: Zooxanthallae is a dinoflagellate.

  12. Continued… 21. What kingdom does coral belong to? 22. What domain do zooxanthellae and plasmodium belong to? 23. What is the skeleton of coral made of? 24. About how many people die from malaria in the tropics every year? 25. In the life cycle of a plasmodium, what do the red blood cells release?
