What is the term for thread like appendages that provide bacteria with motion?

  1. Fimbriae

  2. Flagella

  3. Mesosomes

  4. Mitochondria

The correct answer is: Flagella

Flagella are the thread-like appendages that enable bacteria to move. They are long, whip-like structures that can rotate, allowing the bacterium to swim in liquid environments. This movement plays a critical role in the bacterium's ability to find nutrients, evade harmful substances, and colonize new environments. Fimbriae, on the other hand, are short, hair-like fibers that help bacteria adhere to surfaces but do not provide motility. Mesosomes are structures that were once thought to be invaginations of the bacterial plasma membrane involved in various cellular processes but do not provide movement. Mitochondria are organelles found in eukaryotic cells involved in energy production, and they also do not confer motility to bacteria.
