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.

What is Binary Fission? – Meaning and Definition
Definition:
Binary fission is a type of asexual reproduction in which a single-celled organism divides into two equal and identical daughter cells.
In binary fission, the fully grown parent cell splits into two halves, each becoming a new organism.
In Simple Words:
Binary fission means “splitting into two.”
Just one parent is enough to create two offspring — and they are exact copies (clones) of the parent.
Where Does Binary Fission Happen?
Mostly seen in unicellular organisms, such as:
-
Bacteria
-
Amoeba
-
Paramecium
-
Euglena
Steps in Binary Fission (in Bacteria or Amoeba):
-
DNA replication – The genetic material of the cell makes a copy.
-
Cell growth – The cell grows in size.
-
DNA separates – The two DNA molecules move to opposite sides.
-
Cytoplasm divides – The cell membrane pinches inwards.
-
Two daughter cells – The parent cell splits into two equal parts.
Example:
Amoeba divides by binary fission:
-
Nucleus divides first (karyokinesis)
-
Then the body (cytokinesis)
-
Forms two identical amoebae
Key Characteristics:
| Feature | Binary Fission |
|---|---|
| Type of reproduction | Asexual |
| Number of parents | One |
| Offspring | Genetically identical (clones) |
| Speed | Fast |
| Seen in | Bacteria, Amoeba, Paramecium, etc. |
Fun Fact:
Bacteria can reproduce by binary fission every 20 minutes under ideal conditions!
