Study Notes
Bacterial Structures
- Flagella are long, whip-like structures used for movement in bacterial cells.
- Axial Filaments, also known as Endoflagella, are found in spirochetes, wrapped around the cell body, and are used for corkscrew movement.
Attachment and Genetic Exchange
- Fimbriae are short, bristle-like fibers that sprout off the cell surface, used for attachment.
- Pili are longer than fimbriae, used for attachment and genetic exchange between bacterial cells through a process called conjugation.
