Protists are eukaryotic organisms that are mostly single-celled and can reproduce both sexually and asexually. They are decomposers and consumers. There are three main groups of protists: fungus-like protists, plant-like protists called algae, and animal-like protists called protozoa. Protozoa move using flagella, cilia, pseudopods, or they cannot move if they are parasitic. Some disease-causing protists are Giardia, which causes diarrhea, and Plasmodium, which is carried by mosquitoes and causes malaria.

2. Protist General Facts Types of Protists
1. Eukaryotes
2. Most - single celled
3. Asexually and
sexually reproduction
4. Consumers and
decomposers
1. Fungus like
protists
2. Algae - plant like
protists
3. Protozoa –
animal like
protists

3. Fungus like Protists Plant like protists
Animal-like Protists
1. decomposers
2.Cell wall
3.slime mold, and water
molds
1. Cell wall like plants
2. Chlorophyll for
photosynthesis
3. Phytoplankton, sea
weeds, algae
1. No cell wall
2. Eat food
3. Amoeba, paramecium,
euglena

7. 4 groups
based
on how
move:
Flagella
EX: Giardia
Pseudopods
EX: Amoeba
Cannot move
EX: Parasitic
protozoa like
Plasmodium
(causes malaria)
Cilia
EX: Paramecium

8. Disease Causing Protists
• Giardia—diarrhea
• Amoeba—amebic
dysentery “traveler’s
diarrhea”
• Plasmodium, carried
by mosquitoes—
malaria
• Trypanosome—
Sleeping sickness
