Mesosomes include

Options

A. Vesicles
B. Tubules
C. Lamellae
D. All the above

Answer

To answer the question "Mesosomes include," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mesosomes**:
- Mesosomes are specialized structures found in prokaryotic cells, particularly in bacteria. They are formed by the invagination (infolding) of the plasma membrane.

2. **Identifying Components of Mesosomes**:
- The question provides options: vesicles, tipules, lamellae, and all of the above. We need to analyze these components to see if they are part of mesosomes.

3. **Analyzing the Options**:
- **Vesicles**: Mesosomes can contain vesicles, which are small membrane-bound sacs that transport materials within the cell.
- **Tipules**: This term is less common in the context of mesosomes and may refer to specific structures in certain organisms. However, it is not a widely recognized component of mesosomes.
- **Lamellae**: Mesosomes can also include lamellae, which are layers or sheets of membrane that can be involved in various cellular processes.

4. **Conclusion**:
- Since mesosomes can include vesicles and lamellae, and considering the option "all of the above," it is reasonable to conclude that mesosomes include vesicles, lamellae, and potentially tipules, depending on the context. Therefore, the correct answer is **"all of the above."**

### Final Answer:
Mesosomes include **all of the above**: vesicles, tipules, and lamellae.
