All bacteria have the following organelle

Options

A. Gogi bodies
B. Mesosomes
C. Mitochondria
D. All the above.

Answer

To answer the question "All bacteria have the following organelle," we will analyze the options provided: Golgi bodies, Mesosomes, Mitochondria, or all the above.

### Step-by-Step Solution:

1. **Understanding Bacterial Structure**:
- Bacteria are prokaryotic organisms, which means they lack a true nucleus and membrane-bound organelles. Their genetic material is not enclosed within a nuclear membrane.

2. **Identifying Membrane-Bound Organelles**:
- The options given include Golgi bodies and Mitochondria, both of which are membrane-bound organelles. Since bacteria do not have membrane-bound organelles, these cannot be present in all bacteria.

3. **Examining Mesosomes**:
- Mesosomes are invaginations of the bacterial cell membrane. They are not membrane-bound organelles like Golgi bodies or mitochondria but are structures formed by the cell membrane itself. Mesosomes are involved in various functions, including cell division.

4. **Conclusion**:
- Since all bacteria possess mesosomes and lack Golgi bodies and mitochondria, the correct answer to the question is **Mesosomes**.

### Final Answer:
**Mesosomes** are the organelles that are present in all bacteria.
