Which of the following methods of movement in bacteria are mediated by flagella?
A
Twitching
B
Gliding
C
Swarming
D
Swimming
검증된 단계별 안내1
Understand that bacterial motility can occur through various mechanisms, each involving different cellular structures.
Recognize that flagella are long, whip-like appendages that rotate to propel bacteria through liquid environments, enabling swimming motility.
Identify that swarming is a coordinated movement of bacterial populations across solid or semi-solid surfaces, which also depends on flagella for propulsion.
Note that twitching motility is mediated by type IV pili, not flagella, and involves a jerky movement on surfaces.
Understand that gliding motility is a smooth movement on surfaces that does not involve flagella but other specialized mechanisms.
