Define binary fission. Mention some orgamsms which show this phenomenon.

Explanation

### Step-by-Step Solution:

1. **Definition of Binary Fission**:
- Binary fission is a type of asexual reproduction in which a single organism divides into two identical daughter cells. This process involves the replication of the organism's genetic material followed by the division of the cytoplasm, resulting in two separate entities.

2. **Process of Binary Fission**:
- In binary fission, the organism first duplicates its DNA. Then, the cell elongates, and the cell membrane pinches inward, dividing the cell into two parts. Each part contains one copy of the DNA, leading to the formation of two daughter cells that are genetically identical to the parent cell.
