Here are the answers to the questions.

5. List the Sub-classes found among the ciliates with one example each.

SN	Sub-classes	Examples
1	Holotrichia	Paramecium
2	Peritrichia	Vorticella
3	Spirotrichia	Stentor

6a. Name the locomotory organelles of the following organisms.

SN	Organism	Locomotory organelles

2	Opalina	Flagella
3	Plasmodium	No specialized organelles (gliding motility)
4	Euglena	Flagella
5	Entamoeba	Pseudopodia

6b. State one (1) zoological importance of each member above.

1. Trypanosoma: Causes African sleeping sickness in humans and nagana in livestock.
2. Opalina: Commensal in the intestines of amphibians like frogs.
3. Plasmodium: Causes malaria in humans.
4. Euglena: Important primary producer in aquatic food chains.
5. Entamoeba: Entamoeba histolytica causes amoebic dysentery in humans.

6c. List three (3) diagnostic features of the mastigophorans.

1. Possess one or more flagella for locomotion.
2. Reproduce primarily by longitudinal binary fission.
3. May be free-living, parasitic, or symbiotic; some are photosynthetic.
