Which of the following is NOT a step in the life cycle of a bacterium?
A
Spore formation
B
Growth phase
C
Binary fission
D
Meiosis
Verified step by step guidance1
Step 1: Understand the typical life cycle of a bacterium, which includes phases such as growth, binary fission (cell division), and sometimes spore formation for survival under harsh conditions.
Step 2: Recognize that binary fission is the primary method of reproduction in bacteria, where one cell divides into two identical daughter cells.
Step 3: Note that spore formation is a survival mechanism used by some bacteria to withstand unfavorable conditions, so it is considered part of their life cycle.
Step 4: Identify that meiosis is a type of cell division associated with sexual reproduction in eukaryotic organisms, not bacteria, which reproduce asexually.
Step 5: Conclude that meiosis is NOT a step in the bacterial life cycle because bacteria do not undergo sexual reproduction or meiosis.
