Questions: Multiple Choice Question The diseases malaria and toxoplasmosis are caused by which type of protozoa? Amoebas Flagellates Ciliates Sporozoa Need help? Review these concept resources.

The answer is the fourth one (Sporozoa): the original text in the question...

Explanation for each option:

1. Amoebas: Amoebas are a type of protozoa that move using pseudopodia. They are not responsible for causing malaria or toxoplasmosis. Instead, they are often associated with diseases like amoebic dysentery.

2. Flagellates: Flagellates are protozoa that move using whip-like structures called flagella. While some flagellates can cause diseases (e.g., Giardia), they are not responsible for malaria or toxoplasmosis.

3. Ciliates: Ciliates are protozoa that move using hair-like structures called cilia. They are not known to cause malaria or toxoplasmosis.

4. Sporozoa: Sporozoa are a group of protozoa that reproduce by spore formation. This group includes Plasmodium species, which cause malaria, and Toxoplasma gondii, which causes toxoplasmosis. Therefore, Sporozoa is the correct answer.

In summary, both malaria and toxoplasmosis are caused by protozoa classified as Sporozoa.
