Type of asexual reproduction used by bacteria:
- A.
Fusion
- B.
Binary fission
- C.
Sexual reproduction
- D.
Conjugation
Correct Answer
B. Binary fissionExplanation
Binary fission is the correct answer because it is the most common type of asexual reproduction used by bacteria. In binary fission, a single bacterial cell divides into two identical daughter cells. This process allows bacteria to reproduce rapidly and efficiently, leading to exponential growth of the population. Unlike fusion, which involves the merging of two gametes, binary fission does not involve the fusion of genetic material from two different cells. Similarly, sexual reproduction and conjugation both involve the exchange of genetic material between two different cells, which is not characteristic of bacterial reproduction through binary fission.Rate this question:
