Name the group and one example:
- (a) a cell that flows forward by pushing out false feet
- (b) a slipper-shaped cell covered with cilia, with a cavity that opens outside
- (c) a long cell that lashes a single whip in the blood of a sick person
- (d) a parasite that hides inside red blood cells and spreads by a spore-like stage
Need a reminder? The key ideaShow
Protozoans are heterotrophic protists, predators or parasites. Amoeboid: pseudopodia (Amoeba, Entamoeba). Flagellated: flagella (Trypanosoma, sleeping sickness). Ciliated: cilia and a gullet (Paramecium). Sporozoans: an infectious spore-like stage (Plasmodium, malaria).
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
(a) Pseudopodia: amoeboid, Amoeba.
(b) Cilia and a gullet: ciliated, Paramecium.
(c) A flagellum: flagellated, Trypanosoma.
(d) An infectious spore-like stage: sporozoan, Plasmodium.
