Bacterial flagella have which functions? check all that apply they are the organelle of locomotion for most bacteria capable of motility. a motile response to an environmental stimulus. the flagella function due to makeup of nine microtubule pairs surrounding two central microtubules. the flagella, mitochondria and chloroplasts all move in the same way - by synthesizing atp through proton gradient.

Option A and B. They are the organelle of locomotion for most bacteria capable of motility. And, a motile response to an environmental stimulus. Bacterial flagella are helical filaments made up of the protein flagellin 20-nanometer-thick with a rotary motor at its base which can turn clockwise or counterclockwise. Like the multicellular flagellum the primary role of the flagellum is locomotion, bacterial mobility, but it often functions as a sensory organelle in response to external stimuli like exposure to chemicals and temperatures outside the cell.
