A bacterial cell contains

Options

A. Mesosome, Golgi bodies and nucleoid
B. Mesosome and sap vacoule
C. Mesosome, nucleoid _and thylakoids
D. Lysosome, nucleoid and inclusion bodies

Answer

To answer the question about what is present in a bacterial cell, we can analyze the options provided step by step.

### Step-by-Step Solution:

1. **Understanding Bacterial Cell Structure**:
- Bacterial cells are prokaryotic, meaning they lack a defined nucleus and membrane-bound organelles. They have a simpler structure compared to eukaryotic cells.

2. **Identifying Components**:
- Common components found in bacterial cells include:
- **Mesosomes**: These are invaginations of the plasma membrane and are involved in cellular processes such as respiration and cell division.
- **Nucleoids**: This is the region where the bacterial chromosome (DNA) is located. It is not membrane-bound.
- **Inclusion Bodies**: These are granules of stored nutrients or materials, but they are not membrane-bound organelles.

3. **Evaluating the Options**:
- **Option 1**: Mesosome, colgibodies, and nucleoids.
- Mesosomes and nucleoids are present, but colgibodies do not exist in bacterial cells. Therefore, this option is incorrect.
- **Option 2**: Mesosome and sapvecule.
- Mesosomes are present, but sapvecules (which are found in plant cells) are not. This option is incorrect.
- **Option 3**: Mesosome, nucleoids, and thalacoids.
- Mesosomes and nucleoids are present, and thalacoids are found in cyanobacteria (a type of bacteria). This option is possible.
- **Option 4**: Lysosome, nucleoids, and inclusion bodies.
- Lysosomes are membrane-bound organelles found in eukaryotic cells, not in bacteria. While nucleoids and inclusion bodies are present, this option is incorrect.

4. **Conclusion**:
- The only option that includes components that are consistently found in bacterial cells is Option 3: Mesosome, nucleoids, and thalacoids.

### Final Answer:
The correct answer is **C: Mesosome, nucleoids, and thalacoids**.
