WebJul 14, 2024 · Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and is a key virulence characteristic. Why is the flagella important to the cell? A flagellate can have one or several flagella. Web6. List differences between Prokaryotic and Eukaryotic cells. The differences between the two types of cells are that prokaryotic cells are unicellular and eukaryotic cells are multicellular. Moreover, eukaryotes have a nucleus and membrane-bound organelles, and prokaryotes do not. Eukaryotic DNA is presented in the cell’s nucleus and prokaryotic …
