Bacteria having no flagella are unable to

  • A.move
  • B.reproduce
  • C.stick to tissue surfaces
  • D.grow in nutrient agar

Answer: A

Correct answer: move

Flagella are the organelles of motility, so a bacterium without them cannot swim. It can still reproduce, grow on agar, and adhere - adhesion being the work of fimbriae. (Some non-flagellated bacteria do move by gliding or twitching, but not by swimming.)
