Question 5

Know which ones are algae and which are protozoa

Answer 5

ALGAE: Desmids, Diatoms, Ceratium,

Question 6

Protozoa are generally separated by how they move – do you know who moves by cilia?
(or flagella? or pseudopodia?)

Answer 6

Flagella: Trichomonas,
Pseudopodia: Amoeba,

Question 7

Know which organisms are pathogens and the disease they cause

Answer 7

Trypanosoma
-T. cruzi (chaga’s ❤️disease)
-T. brucei ( African sleeping sickness)
Plasmodium (malaria)

3. RBC’s explode & release babies cause fever
