Who is responsible for extensive compartmentalisation of cytoplasm in eukaryotic cell?

Answer

**Step-by-Step Solution:**

1. **Understanding Eukaryotic Cells:**
- Eukaryotic cells are characterized by having a well-defined nucleus. This distinguishes them from prokaryotic cells, which do not have a nucleus.

2. **Cytoplasm Definition:**
- The cytoplasm is the fluid that surrounds the nucleus within the cell. It contains various components, including organelles.

3. **Compartmentalization of Cytoplasm:**
- Eukaryotic cells exhibit extensive compartmentalization of the cytoplasm. This means that the cytoplasm is divided into distinct areas or compartments, each serving different functions.

4. **Role of Membrane-Bound Organelles:**
- The compartmentalization in eukaryotic cells is primarily due to the presence of membrane-bound organelles. These organelles are specialized structures within the cytoplasm that are enclosed by membranes.

5. **Examples of Membrane-Bound Organelles:**
- Some examples of these organelles include:
- Endoplasmic Reticulum (ER)
- Golgi Apparatus
- Mitochondria
- Vacuoles
- Lysosomes
- Ribosomes (though ribosomes are not membrane-bound, they also contribute to the compartmentalization in terms of function).

6. **Conclusion:**
- Therefore, the extensive compartmentalization of the cytoplasm in eukaryotic cells is due to the presence of these membrane-bound organelles.

**Final Answer:**
The extensive compartmentalization of the cytoplasm in eukaryotic cells is primarily due to the presence of membrane-bound organelles.
