Study Notes
Protists
- Protists are eukaryotic, meaning they have a nucleus
- Protists are neither plants nor animals
- They are unicellular organisms
- They are categorized into four "Supergroups"
- Protists can be heterotrophs, autotrophs, or decomposers
Protozoans (animal-like Protists)
- Protozoans are unicellular and eukaryotic
- Protozoans are heterotrophic
- They are motile
- Sarcodinians move using pseudopods, which are extensions of their cytoplasm. An example is amoeba
- Zooflagellates propel themselves using flagella, which are whip-like structures. Trypanosoma, which causes African Sleeping Sickness, is a zooflagellate that lives in tsetse flies
- Ciliates are the largest group of protozoans. They have hair-like cilia that cover their bodies. An example is Paramecium
- Sporozoans are parasitic protozoans that do not move. They reproduce both sexually and asexually. An example is Plasmodium, which causes malaria
