- Be able to contrast vesicular and compact nuclei.
- Explain the transition of ectoplasm and endoplasm in ameboid movement.
- Explain the current hypothesis in the role of actin in ameboid movement.
- Contrast lobopodia, filipodia, reticulopodia, and axopodia.
- Compare the structure of an axoneme of a cilium with a kinetosome.
- Explain the sliding–microtubule hypothesis.
- Explain the processes of eating, digestion, osmoregulation, and respiration in protozoans.
- Contrast binary fission, budding, multiple fission, and sexual and asexual reproduction.
