Unicellular Heterotrophic Protists
Referred to as protozoa. All protozoa lack cell walls
Photoautotrophic Protists
Referred to as algae. Free living and contain cell walls
Supergroup Excavata
- Diverse
- All are unicellular
- All have flagella
- Modified mitochondria
- Anaerobic metabolism
Giardia Intestinalis
Belong to Supergroup Excavata
-cause giardiasis
Trichomonas vaginalis
Belong to Supergroup Excavata
-parasitic protozoan that causes vaginal infections in about 180 million women globally
Trypanosoma
Belong to Supergroup Excavata
- Parasitic protozoa that cause trypanosomiasis (African Sleeping Sickness)
- It is transmitted to humans from the tsetse fly
Leishmania
Belong to Supergroup Excavata
- parasitic protozoa that causes leishmaniasis in humans
- Cutaneous Leishmaniasis- skin sores
- Visceral Leishmaniasis- fatal infection of organs
- transmitted by the bite of a sand fly
Euglena
Belong to Supergroup Excavata
- Unicellular algae
- presence of eye spots
- mixotrophic
Supergroup Chromalveolata
-Highly diverse
- May have originated by secondary endosymbiosis
-Unicellular photosynthetic organisms
-Multicellular photosynthetic organisms
-Unicellular heterotrophic organisms
-Unicellular parasitic organisms
Examples – Ciliates, Diatoms, Dinoflagellates, Oomycetes. Brown Algae, Apicomplexans
Supergroup Rhizarians
- Amoebas with thread like pseudopodia and mineral shells (tests)
- Examples – Foraminiferans sp., Radiolarians sp.
- Diverse group with DNA similarities
Supergroup Archaeplastida
- Primary Endosymbiosis
- Closest relatives of land plants
Examples – Green Algae, Red Algae
Supergroup Unikonts
-Claim to Fame - Protists most closely related to land animals and fungi
Examples – Amoeba sp., Entamoeba sp., Slime Molds
Flagellated Parasitic Protozoans
- Giardia intestinalis
- Trichomonas vaginalis
- Trypanosoma
- Leishmania
