Eukaryotic cell differ from prokaryotic cell in having

Options

A. membrane bound organelles
B. membrane bound nucleus
C. both 1 and 2
D. dense matrix of cytoplasm

Answer

### Step-by-Step Solution:

1. **Understanding Cell Types**:
- Eukaryotic cells and prokaryotic cells are the two main types of cells. Eukaryotic cells can be unicellular or multicellular, while prokaryotic cells are primarily unicellular.

2. **Cell Structure**:
- Eukaryotic cells have a well-developed cell structure, which includes various membrane-bound organelles. In contrast, prokaryotic cells have a simpler structure without membrane-bound organelles.

3. **Membrane-bound Organelles**:
- One of the key differences is that eukaryotic cells contain membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria, and lysosomes. Prokaryotic cells lack these organelles.

4. **Nucleus**:
- Eukaryotic cells have a well-defined nucleus that is membrane-bound. This nucleus houses the cell's genetic material (DNA). In prokaryotic cells, the genetic material is not enclosed in a membrane-bound nucleus.

5. **Histone Proteins**:
- Eukaryotic cells contain histone proteins that help in the packaging of DNA. This is not a feature of prokaryotic cells, where DNA is not associated with histones.

6. **Plasmid DNA**:
- Plasmid DNA is common in prokaryotic cells but is not typically found in eukaryotic cells. This is another distinguishing feature.

7. **Conclusion**:
- Therefore, eukaryotic cells differ from prokaryotic cells in having membrane-bound organelles and a well-defined, membrane-bound nucleus.

### Final Answer:
Eukaryotic cells differ from prokaryotic cells in having membrane-bound organelles and a well-defined nucleus.
