Prokaryotes vs. Eukaryotes

Bacteria are prokaryotes, meaning they do not have a nucleus or membrane-bound organelles.
Protists are eukaryotes, meaning they have a nucleus.

Protists

Mostly unicellular organisms.
Not classified as plants or animals.
Divided into four supergroups.
Can be heterotrophs (animal-like), autotrophs (plant-like), or decomposers (fungus-like).

Protozoans (Animal-like)

Unicellular, eukaryotic, heterotrophic protists.
Can move.

1. Sarcodines

Move by extending cytoplasm or a "false foot" called a pseudopod.
Example: Amoeba.

2. Zooflagellates

Use whip-like extensions called flagella for movement.
Example: Trichmympha (lives in termite guts, helps digest cellulose), Trypanosama (lives in tsetse flies, causes African Sleeping Sickness).

3. Ciliates

Largest group of protozoans.
Bodies covered in tiny hair-like projections called cilia.
Example: Paramecium.

4. Sporozoans

Do not move.
Spore-forming parasitic protozoans.
Live by being parasites on or in animals.
Can reproduce sexually and asexually.
Example: Plasmodium (causes malaria).
Immature sporozoans are called sporozoites and can be transmitted through fluids from one host to another.

Prokaryotic vs. Eukaryotic Cells

Prokaryotes lack a nucleus and membrane-bound organelles
Eukaryotes possess a nucleus and membrane-bound organelles

Protists

Mostly unicellular organisms, but eukaryotic
Previously classified in their own kingdom, Protista
Now divided into 4 "Supergroups"
Can either be heterotrophs, autotrophs, or decomposers

Protozoans (Animal-like Protists)

Unicellular
Eukaryotic
Heterotrophs
Motile

Sarcodines

Move using cytoplasmic extensions called pseudopods
Example: Amoeba

Zooflagellates

Use whip-like flagella for movement
Example: Trichmympha (digests cellulose in termites)
Example: Trypanosama (causes African Sleeping Sickness, transmitted by tsetse flies)

Ciliaphorans (Ciliates)

Largest group of protozoans
Covered in tiny hair-like cilia for movement
Example: Paramecium

Sporozoans

Non-motile, parasitic protozoans
Form spores
Can reproduce sexually and asexually
Example: Plasmodium (causes malaria)
Immature sporozoans (sporozoites) are transmitted through fluids
