Question

Which of these combinations is correct about protozoans?

• A. Entamoeba - Sporozoan; Paramecium - Ciliated protozoan
• B. Plasmodium - Sporozoan; Trypanosoma - Ciliated protozoan
• C. Paramecium - Ciliated protozoan; Trypanosoma - Flagellated protozoan
• D. Entamoeba - Ciliated protozoan; Plasmodium - Flagellated protozoan

Answer 1

Answer: (C)

Entamoeba is an intestinal parasite in humans and is a part of amoeboid protozoans. Plasmodium causes malaria and is a sporozoan since it has a spore-like infective stage in its life cycle. Trypanosoma which causes sleeping sickness has flagella, and hence, it is a flagellated protozoan. Paramecium is an aquatic, actively moving organism because of the presence of thousands of cilia. Hence, it is a ciliated protozoan.
