What are the sex organs provided in some bacteria ?

Options

A. circular DNA
B. plasmid
C. sex pili
D. gametes/F factor

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the sex organs provided in some bacteria. We need to identify which of the given options functions as a sex organ in bacteria.

2. **Analyzing the Options**:
- **Circular DNA**: This refers to the nuclear DNA present in bacteria. It carries genetic information but does not function as a sex organ.
- **Plasmids**: These are extra-chromosomal DNA molecules found in bacteria. They play a role in processes like transformation but are not considered sex organs.
- **Sex Pili**: These are hair-like structures that protrude from the bacterial cell wall. They are crucial for the process of conjugation, where they help form a conjugation tube to transfer genetic material between bacteria.
- **Gametes**: These are reproductive cells in higher organisms and are not applicable to bacteria.
- **F Factor (F Plasmid)**: This is a set of genes that encode for the formation of sex pili but is not a sex organ itself.

3. **Identifying the Correct Answer**: Based on the analysis, the sex organ in bacteria is the **Sex Pili**. They are specifically involved in the process of conjugation, allowing for the transfer of genetic material.

4. **Conclusion**: The correct answer to the question is **Sex Pili**.
