Nucleoli are not found in

Options

A. Blue green algae
B. Maize
C. Pancreas
D. Fungi

Answer

**Step-by-Step Solution:**

1. **Understanding Nucleolus**: The nucleolus is a small, dense, spherical structure located within the nucleus of eukaryotic cells. It is primarily involved in the synthesis of ribosomal RNA (rRNA) and the assembly of ribosomes.

2. **Identifying the Context**: The question asks where nucleoli are not found. To answer this, we need to consider the types of cells that possess or lack a nucleolus.

3. **Differentiating Cell Types**:
- Eukaryotic cells (like those in plants, animals, and fungi) contain a nucleus and, consequently, a nucleolus.
- Prokaryotic cells (like bacteria and archaea) do not have a nucleus; instead, their genetic material is located in a nucleoid region.

4. **Analyzing the Options**: The question likely provides several options. Among them, if "blue-green algae" (also known as cyanobacteria) is listed, it should be identified as a prokaryote. Since prokaryotes do not have a nucleus, they also do not have a nucleolus.

5. **Conclusion**: Therefore, the correct answer to the question "Nucleoli are not found in" is "blue-green algae" or cyanobacteria, as they are prokaryotic organisms.

**Final Answer**: Nucleoli are not found in blue-green algae (cyanobacteria).
