Bacteria that lack fimbriae are less likely to:

• A. move using flagella
• B. produce endospores
• C. adhere to surfaces
• D. carry out photosynthesis

Answer: (C)

Verified step by step guidance

1. Understand the function of fimbriae in bacteria: fimbriae are hair-like appendages that primarily help bacteria adhere to surfaces, including host tissues and other cells.
2. Recognize that fimbriae are not involved in bacterial motility; movement is typically facilitated by flagella, which are structurally and functionally different from fimbriae.
3. Know that endospore production is a survival mechanism unrelated to fimbriae; it involves the formation of a tough, dormant structure inside the bacterial cell.
4. Recall that photosynthesis in bacteria is carried out by specialized pigments and cellular structures, not by fimbriae.
5. Conclude that bacteria lacking fimbriae would be less likely to adhere to surfaces, as fimbriae are specifically adapted for attachment.
