Bacterial cells move by flagellar motion in response to chemical signals during which process?

• A. chemotaxis
• B. binary fission
• C. conjugation
• D. sporulation

Answer: (A)

Verified step by step guidance

1. Understand the question is asking about the process by which bacterial cells move using their flagella in response to chemical signals.
2. Recall that bacterial movement toward or away from chemical stimuli is called chemotaxis, which involves flagellar motion.
3. Recognize that binary fission is a process of bacterial cell division, not movement.
4. Know that conjugation is a form of genetic exchange between bacteria, not related to movement.
5. Identify that sporulation is the formation of spores, a survival mechanism, and not related to flagellar movement or response to chemicals.
