Which one is not a difference between Prokaryotic and Eukaryotic cell?...
The presence of cell walls is not an exclusive difference between prokaryotic and eukaryotic cells. Both prokaryotic cells and some eukaryotic cells, such as plant cells, can have cell walls. Therefore, option 4 is the correct answer as it does not represent a difference between prokaryotic and eukaryotic cells.

Which one is not a difference between Prokaryotic and Eukaryotic cell?...
Understanding Prokaryotic and Eukaryotic Cells
Prokaryotic and eukaryotic cells are the two fundamental types of cells that make up all living organisms. While they have several distinct differences, the presence of a cell wall is not one of them.
Common Presence of Cell Walls
- Prokaryotic cells, such as bacteria, often have a cell wall made of peptidoglycan, which provides structure and protection.
- Eukaryotic cells, particularly in plants and fungi, also possess a cell wall. In plants, it is primarily made of cellulose, while in fungi, it is composed of chitin.
Key Differences Between Prokaryotic and Eukaryotic Cells
- Presence of Membrane-Bounded Organelles:
- Prokaryotic cells lack membrane-bound organelles, whereas eukaryotic cells contain distinct organelles like the nucleus, mitochondria, and endoplasmic reticulum.
- Number of Chromosomes:
- Prokaryotic cells typically have a single, circular chromosome, while eukaryotic cells have multiple, linear chromosomes enclosed within a nuclear membrane.
- Presence of Nuclear Membrane:
- Prokaryotic cells do not have a nuclear membrane; their genetic material is not separated from the cytoplasm. In contrast, eukaryotic cells have a defined nucleus surrounded by a nuclear membrane.
Conclusion
In summary, while the presence of cell walls is common in both prokaryotic and eukaryotic cells, the other options listed highlight significant differences. Understanding these distinctions is crucial for biology, particularly in fields like microbiology and cellular biology.
