The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Nucleolus**: The nucleolus is a prominent structure found within the nucleus of eukaryotic cells. It is not surrounded by a membrane, which distinguishes it from other organelles. 2. **Identifying Key Features**: The nucleolus has several key characteristics: - It is **spherical** in shape. - It is **colloidal**, meaning it has a gel-like consistency. - It is **acidophilic**, which means it has an affinity for acidic dyes, indicating that it contains RNA and proteins. 3. **Evaluating Options**: - **Option 1**: "Dense acidophilic body" - This is correct as the nucleolus is dense and acidophilic. - **Option 2**: "Present in cytoplasm" - This is incorrect because the nucleolus is located in the nucleus, not the cytoplasm. - **Option 3**: "Spherical colloidal and basophilic body" - While it is spherical and colloidal, it is not basophilic; therefore, this option is incorrect. - **Option 4**: "A membrane-bound structure" - This is incorrect as the nucleolus is non-membrane bound. 4. **Conclusion**: Based on the evaluation of the options, the correct answer is that the nucleolus is a **dense acidophilic body**. **Final Answer**: The nucleolus is a dense acidophilic body. ---
