Non - membrane bounded cell organelle only found in animal cell is

Options

A. Ribosomes
B. Nucleolus
C. Centriole
D. Lysosomes

Answer

To solve the question "Non-membrane bounded cell organelle only found in animal cell is," we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding Non-Membrane Bounded Organelles**:
- Non-membrane bounded organelles are those that do not have a surrounding membrane. This is an important characteristic to consider when evaluating the options.

2. **Evaluating the First Option - Ribosomes**:
- Ribosomes are indeed non-membrane bounded organelles. They are found in both prokaryotic and eukaryotic cells, including plant and animal cells. Therefore, this option is incorrect for the question as it is not exclusive to animal cells.

3. **Evaluating the Second Option - Nucleolus**:
- The nucleolus is a non-membrane bounded structure found within the nucleus of eukaryotic cells. It is involved in the synthesis of ribosomal RNA. However, it is not exclusive to animal cells, as it is also present in plant cells. Thus, this option is also incorrect.

4. **Evaluating the Third Option - Centriole**:
- Centrioles are non-membrane bounded organelles that are primarily found in animal cells. They play a crucial role in cell division by helping in the formation of the spindle fibers that separate chromosomes. This makes centrioles the correct answer to the question.

5. **Evaluating the Fourth Option - Lysosome**:
- Lysosomes are membrane-bound organelles that contain digestive enzymes. They are often referred to as "suicidal bags" due to their role in breaking down waste materials and cellular debris. Therefore, this option is incorrect.

### Conclusion:
Based on the evaluation of all options, the correct answer to the question is **Centriole**.

### Final Answer:
The non-membrane bounded cell organelle only found in animal cells is **Centriole**.
