Question

Binary fission is a type of
a. Sexual reproduction
b. Asexual reproduction
c. Vegetative propagation
d. Nuclear fragmentation

Answer 1

Hint: Binary fission is a process in which the parent organism divides into two halves, each half forming an independent daughter organism. It occurs in many single celled organisms such as bacteria, amoeba and paramecium.

Complete answer:
Binary fission is a type of asexual reproduction. Asexual reproduction is a mode of reproduction in which new individuals develop from a single parent.

Features of sexual reproduction:
- There is involvement of only one parent (uniparental).
- It can occur with or without gamete formation.
- It involves only mitotic division.

There are different ways of asexual reproduction:
- Binary fission
- Budding
- Sporulation
- Vegetative reproduction/propagation

Binary fission is the process of a parent cell divides into two daughter cells. It involves amitosis in bacteria and mitotic division of nucleus in yeast and amoeba.
Binary fission is divided into three types on the basis of plan of division:
> Simple/Irregular binary fission: In this fission, division can occur through any plane, e.g., Amoeba.
> Longitudinal binary fission: The plane of division passes along the longitudinal axis of the organism, e.g., Euglena.
> Transverse binary fission: The plane of division runs along the transverse axis of the individual, e.g., Bacteria, paramecium and diatoms.

Hence, the correct answer is option (B).

Note: The offspring/individual produces during asexual reproduction are exact copies of each other and their parents because it inherits all the chromosomes from one parent. Such a group of morphologically and genetically similar individuals is called clone.
