What are the hair-like appendages present on the surface of many Gram-negative bacteria called?

-✅Explanation: Fimbriae are thin, hair-like appendages found on the surface of many Gram-negative bacteria. They play a role in adhesion, allowing bacteria to attach to surfaces or other cells.
–

📌Other Options Explanations:
-(b) Flagella: Flagella are longer, whip-like structures used by some bacteria for motility. While some Gram-negative bacteria can have flagella.
-(c) Hyphae: Hyphae are thread-like structures that form the body of fungi.

🔑Key Points:
-The Fimbriae are small hair-like structures present all over the body wall.
-This structure of bacteria helps attachment with the host.
-It is made up of protein.
-Fimbriae are long filamentous polymeric protein structures located at the surface of bacterial cells.
-It functions as adhesins to assist binding of the bacteria to a specific receptor on host cells.
