Read the FAQ explanation of Comprehensible InputReal Context
Flagellum is a slender, whip-like appendage found on certain bacteria, protozoa, and other single-celled organisms. It functions as a locomotive organelle, rotating or beating to propel the cell through water. In many organisms, the term can also refer to a hair-like filament on cell surfaces that helps in movement or feeding. In microbiology, the flagellum is a complex structure consisting of a basal body, a hook, and a filament, powered by a motor embedded in the cell membrane. Learning about flagella highlights how diverse microbial movement can be.
Usage Reminders
- Pronounce flagellum as 'fuh-JEL-um'. It is a scientific noun. The plural is flagella. Use in biology or microbiology contexts. Do not confuse with cilia. Remember the three parts: basal body, hook, filament.
Common Misconceptions
- Flagellum is present on all bacteria.
- Flagellum and cilia are the same thing.
- Flagellum is only a tail and has no other parts.
