Monerans possess

Options

A. Nucleosomes
B. Dictyosomes
C. Mesosomes
D. Microsomes

Answer

To determine what Monerans possess, we will analyze the options given in the question based on the characteristics of Monerans.

### Step-by-Step Solution:

1. **Identify Characteristics of Monerans**:
- Monerans are unicellular organisms.
- They are classified as prokaryotes, meaning they lack a true nucleus and membrane-bound organelles.

2. **Evaluate the Options**:
- **Nucleosomes**:
- Nucleosomes are structures found in eukaryotic cells, consisting of DNA wrapped around histone proteins. Since Monerans are prokaryotic, they do not possess nucleosomes.
- **Conclusion**: This option is incorrect.

- **Dictiosomes**:
- Dictiosomes are associated with the Golgi apparatus in eukaryotic cells and are not found in prokaryotic organisms.
- **Conclusion**: This option is also incorrect.

- **Microsomes**:
- Microsomes are fragments of the endoplasmic reticulum found in eukaryotic cells, particularly in liver cells (hepatocytes). Since Monerans are prokaryotic, they do not have microsomes.
- **Conclusion**: This option is incorrect as well.

- **Mesosomes**:
- Mesosomes are invaginations of the bacterial cell membrane and are found in prokaryotic cells (Monerans). They are involved in various cellular processes, including respiration and cell division.
- **Conclusion**: This option is correct.

3. **Final Answer**:
- Monerans possess **mesosomes**.
