Organelle ribosomes resemble

Options

A. Organelle ribosomes of prokaryotes
B. Cytoribosomes of prokaryotes
C. cytoribosomes of eukaryotes
D. all of the above

Answer

### Step-by-Step Solution:

1. **Understanding Ribosomes**: Ribosomes are cellular organelles that are essential for protein synthesis. They are composed of ribosomal RNA (rRNA) and proteins.

2. **Identifying the Types of Ribosomes**:
- In prokaryotic cells, ribosomes are often referred to as cytoribosomes or prokaryotic ribosomes.
- In eukaryotic cells, ribosomes are found in the cytoplasm and are involved in translating mRNA into proteins.

3. **Analyzing the Options**:
- **Option 1: Organelle ribosomes of prokaryotes**: This option is incorrect because it does not specifically refer to the ribosomes that resemble those in eukaryotes.
- **Option 2: Cytoribosomes of prokaryotes**: This is the correct option, as cytoribosomes in prokaryotes are structurally similar to ribosomes found in eukaryotes.
- **Option 3: Cytoribosomes of eukaryotes**: This option is incorrect because cytoribosomes refer to those in prokaryotes, not eukaryotes.
- **Option 4: All of the above**: This option is incorrect since only the second option is correct.

4. **Conclusion**: Based on the analysis, the organelle that resembles ribosomes is the **cytoribosomes of prokaryotes**.

### Final Answer:
The correct answer is **Cytoribosomes of prokaryotes**.
