Non membrane bound organelles found both in eukaryotic and prokaryotic cell is

Options

A. Ribosomes
B. Nucleolus
C. Chromosomes
D. Plasmids

Answer

To answer the question "Non membrane bound organelles found both in eukaryotic and prokaryotic cells is?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Cells**:
- Prokaryotic cells are unicellular organisms with a primitive structure and lack membrane-bound organelles.
- Eukaryotic cells can be unicellular or multicellular and have a more complex structure with membrane-bound organelles.

2. **Identify the Organelles**:
- We need to identify organelles that are not surrounded by membranes and are present in both types of cells.

3. **Evaluate the Options**:
- **Ribosomes**: These are non-membrane bound organelles. They are present in both prokaryotic cells (70S ribosomes) and eukaryotic cells (80S ribosomes). This option is a strong candidate.
- **Nucleolus**: This is found in eukaryotic cells and is not present in prokaryotic cells, so this option is incorrect.
- **Chromosomes**: While chromosomes are present in both types of cells, they are considered membrane-bound structures in eukaryotes, making this option incorrect.
- **Plasmids**: These are found in prokaryotic cells but are not present in eukaryotic cells, so this option is also incorrect.

4. **Conclusion**:
- The only non-membrane bound organelle that is found in both eukaryotic and prokaryotic cells is **Ribosome**. Therefore, the correct answer is option 1: Ribosome.

### Final Answer:
The non-membrane bound organelle found both in eukaryotic and prokaryotic cells is **Ribosome**.
