Binary fisssion is a type of ____ reproduction?
A
asexual
B
sexual
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

Detailed explanation-2: -The type of reproduction in which only a single parent is involved is called asexual reproduction. Binary fission is a method of asexual reproduction in which an animal reproduces by dividing itself into two individuals.

Detailed explanation-3: -In biology, binary fission is a type of asexual reproduction where a parent cell divides, resulting in two identical cells, each having the potential to grow to the size of the original cell. The word asexual describes a reproduction that occurs without involving sex cells (gametes).

Detailed explanation-4: -Binary fission is a mode of vegetative reproduction, in which simple cell division takes place. The unicellular forms like diatoms, yeast, slime moulds, etc., multiply by this process.

Detailed explanation-5: -Amoeba and euglena exhibit binary fission. It is one of the simplest and uncomplicated methods of asexual reproduction. The parent cell divides into two, each daughter cell carrying a nucleus of its own that is genetically identical to the parent. The cytoplasm also divides leading to two equal-sized daughter cells.
