Prokaryotic vs Eukaryotic Cells: Key Differences

Prokaryotic cells, such as bacteria, exhibit several features that distinguish them from eukaryotic cells. One key feature of prokaryotic cells that is not found in eukaryotic cells is the presence of pili. Pili are hair-like structures on the cell surface that aid in adhesion to other cells and surfaces. They also play a crucial role in DNA transfer during conjugation in bacteria.

Cell walls are another distinguishing feature of prokaryotic cells. While prokaryotic cells typically have cell walls, eukaryotic cells do not, except for plant cells. The cell wall provides rigidity and structural support to prokaryotic cells.

Flagella are also common in prokaryotic cells, allowing them to move and navigate their environment. Although eukaryotic cells may possess flagella, they are structurally different from those found in prokaryotic cells. Additionally, eukaryotic cells may have organelles that prokaryotic cells lack, such as a true nucleus and membrane-bound organelles.

In conclusion, the distinct feature unique to prokaryotic cells among the listed options is pili. While prokaryotic cells share some features with eukaryotic cells, such as flagella and DNA, pili are specific to prokaryotes. Understanding these differences between prokaryotic and eukaryotic cells is crucial for grasping the fundamental principles of cell biology.
