Which of the following describes the process by which bacteria divide and multiply, resulting in two identical daughter cells?
- AConjugation
- BBinary Fission
- CMeiosis
- DBudding
Show answer & explanationAnswer & explanation
Correct answer: B. Binary Fission
Binary fission is the primary method of reproduction for bacteria. It is an asexual process where a single bacterial cell divides into two identical daughter cells.
Why the other options are wrong
- A. Conjugation is a process of genetic material transfer between bacterial cells, not a primary method of multiplication.
- C. Meiosis is a type of cell division that produces four haploid cells (gametes) in sexually reproducing organisms, not bacteria.
- D. Budding is a form of asexual reproduction seen in some yeasts and hydra, where a new organism develops from an outgrowth or bud, not typical for bacteria dividing into two equal cells.
Binary Fission
An asexual reproductive process primarily used by bacteria, where a single cell divides into two identical daughter cells after replicating its genetic material.
- Asexual reproduction
- Produces two identical daughter cells
- Primary method for bacteria
Memory trick: Bacteria Break into Two, Binary Fission is the clue.
