The only organelle found in PPLO is

Options

A. nucleus
B. ribosomes
C. plastids
D. vacuoles

Answer

To solve the question regarding the only organelle found in PPLO (Pleuro Pneumonia Like Organisms), we can follow these steps:

### Step-by-Step Solution:

1. **Understand what PPLO is**:
- PPLO stands for Pleuro Pneumonia Like Organisms. These are a type of bacteria that are classified as prokaryotes.

2. **Identify the characteristics of prokaryotes**:
- Prokaryotes are organisms that do not have membrane-bound organelles. This means they lack structures such as a nucleus, plastids, and vacuoles which are typically found in eukaryotic cells.

3. **Examine the options provided**:
- The options given are:
- Nucleus
- Ribosome
- Plastid
- Vacuoles

4. **Analyze each option**:
- **Nucleus**: This is a membrane-bound organelle found in eukaryotic cells, not in prokaryotes.
- **Ribosome**: This is a non-membrane-bound organelle that is present in both prokaryotic and eukaryotic cells. It is responsible for protein synthesis.
- **Plastid**: These are found in plant cells and are involved in photosynthesis and storage. They are not present in prokaryotes.
- **Vacuoles**: These are storage organelles found in eukaryotic cells, particularly in plant cells.

5. **Conclusion**:
- Since ribosomes are the only organelles that are present in prokaryotes, the correct answer is **ribosome**.

### Final Answer:
The only organelle found in PPLO is **ribosome**.
