Question

A form of asexual reproduction used by a single-celled organism to produce two identical daughter cells.

• A. multiple fission
• B. binary fission
• C. fragmentation
• D. regeneration

Answer 1

The correct option is B

binary fission

The correct option is B:

Explanation of correct option-

1. Binary fission is an asexual reproduction where a single-celled organism divides to form to two daughter cells.
2. First, the nucleus divides into two and then the cytoplasm divides forming two separate individuals.
3. Example- amoeba

Explanation of incorrect option

Option A-

1. Multiple fission is an asexual reproduction where a single-celled organism divides to form more than two daughter cells.
2. Example- bacteria.

Option C-

1. Fragmentation is a type of asexual reproduction where an organism is ribbon-like and it breaks off into two or many pieces.
2. Each fragment then regrows into a new individual.
3. Example- Spirogyra

Option D-

1. Regeneration is a type of asexual reproduction where an organism is capable of regrowing its missing or lost parts.
2. Example- Hydra, Planaria.

Final answer: A form of asexual reproduction used by a single-celled organism to produce two identical daughter cells is binary fission.
