What feature of the prokaryotic cell helps the cell to stick to surfaces?

Explanation:

Flagella is the feature of the prokaryotic cell that helps the cell to stick to surfaces. Flagella are long, whip-like structures that protrude from the surface of the cell and aid in movement. In addition to helping the cell move, flagella also help the cell adhere to surfaces.

When a prokaryotic cell wants to stick to a surface, it extends its flagella and uses them to anchor itself to the surface. This allows the cell to maintain its position and avoid being washed away by fluid flow. The flagella act as a kind of "hook" that keeps the cell attached to the surface.

Overall, flagella play a crucial role in allowing prokaryotic cells to interact with their environment. They help the cell move towards nutrients or away from harmful substances, and they also help the cell adhere to surfaces when needed.
