Study Notes
Protozoan Structure and Function
- Contractile vacuole is responsible for waste excretion in a protozoan.
- The ectoplasm is the relatively clear and firm region of the cytoplasm in a protozoan.
- The pellicle provides structural support and protection to the protozoan cell.
- The cytopharynx is a specialized region involved in the process of phagocytosis, where the protozoan engulfs and digests food particles.
Protozoan-Related Diseases
- Primary amebic meningoencephalitis in humans is primarily caused by infection with the protozoan Naegleria fowleri.
