Symbiotic Relationships

Lindsey Suttle, Mehran Hazeer, and Farvah Khaja

SymbiosisMeans “living together”

Symbiont: smaller participant

Host

There are not 3 definite categories of symbiotic relationships, some relationships overlap

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

Zooxanthellae Single-celled plants

Part of dinoflagellates

Mutualism with coralsProtection, 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

Plasmodium Protozoan parasite

Causes malaria

300 million are infected in the tropics and 2 million die from the disease

EvasiveHides from immunes system

Liver and blood cells

Continually changes “face” Vaccines Plasmodium in red blood cells

Life Cycle of Plasmodium
