Binary Fission: Meaning and Definition
Binary Fission is a type of asexual reproduction in which a single fully grown parent cell splits into two identical daughter cells. It is commonly observed in unicellular organisms like bacteria, amoeba, and paramecium.
Definition:
“Binary fission is a process of asexual reproduction in which a single parent cell divides into two genetically identical daughter cells, each inheriting a complete copy of the parent’s DNA.”
Process of Binary Fission:
DNA Replication – The genetic material (DNA) of the parent cell duplicates.
Cell Growth – The parent cell enlarges as the copied DNA moves to opposite ends.
Cytoplasmic Division – The cytoplasm divides, forming a partition.
Daughter Cells Formation – The parent cell splits into two identical cells.
Types of Binary Fission:
Simple Binary Fission – Equal division (e.g., Bacteria).
Transverse Binary Fission – Division across the short axis (e.g., Paramecium).
Longitudinal Binary Fission – Division along the long axis (e.g., Euglena).
Irregular Binary Fission – No specific axis of division (e.g., Amoeba).
Examples of Organisms Using Binary Fission:
- Bacteria
- Amoeba
- Paramecium
- Euglena
Key Features of Binary Fission:
Fast Reproduction – Occurs rapidly under favorable conditions.
No Genetic Variation – Offspring are exact clones of the parent.
Energy Efficient – No need for a mate or gametes.
