Question

Bacteria commonly reproduce vegetatively by

• A. Binary fission
• B. Conjugation
• C. Oidia
• D. Budding

Answer 1

The correct option is A

Binary fission

The correct option is A.

Explanation of the correct option:

1. Bacteria are the most abundant, unicellular, prokaryotic organisms.
2. Bacteria reproduce vegetatively by binary fission.
3. In binary fission, firstly the organism duplicates the genetic materials and then the body divides to form two daughter cells.

Explanation of the incorrect option:

Option B:

1. Conjugation is a mode of sexual reproduction in bacteria.
2. In this process, the genetic materials transfer between two bacterial cells through a conjugation tube.

Option C:

Oidia is an asexual spore found in the fungi.

Option D:

1. Budding is a kind of asexual reproduction occurs in yeast, hydra, etc.
2. In budding, a new daughter cell develops from bud due to cell division at one particular site. After maturation, the daughter bud is detached from the parent body.

Final Answer:

Bacteria commonly reproduce vegetatively by binary fission.
