In the context of fimbriae and hami, which bacterial structure primarily helps bacteria adhere (stick) to surfaces and host tissues?

• A. Ribosomes
• B. Fimbriae (pili)
• C. Endospores
• D. Flagella

Answer: (B)

Verified step by step guidance

1. Understand the function of each bacterial structure listed: ribosomes, fimbriae (pili), endospores, and flagella.
2. Recall that ribosomes are involved in protein synthesis inside the cell and do not play a role in adhesion to surfaces.
3. Recognize that endospores are dormant, resistant structures that help bacteria survive harsh conditions but are not involved in sticking to surfaces.
4. Know that flagella are primarily used for bacterial motility, allowing bacteria to move, rather than adhere to surfaces.
5. Identify fimbriae (also called pili) as hair-like appendages on the bacterial surface that facilitate adhesion to surfaces and host tissues, enabling colonization and infection.
