Work Step by Step
The following are some of the bacterial locomotion and external structures and their descriptions:
Phototaxis- A response of some bacteria to move toward or away from light;
Flagellum- Long, thin, helical appendage used for movement;
Conjugation pili- Tiny, hollow projection that attaches two cells, providing a conduit for exchange of genetic material;
Slime layer- Thin glycocalyx that prevents dehydration, traps nutrients, and allows for attachment to other cells and objects in the environment;
Chemotaxis- Nonrandom response of movement toward or away from chemical concentration gradients in the environment;
Glycocalyx- Term used to describe all polysaccharide-containing substances external to the cell wall;
Axial filament- Spirochete endoflagella causing corkscrew motion;
Capsule- A thick, protective polysaccharide containing structure located outside of the cell wall.
