WebMay 15, 2024 · The base of cilia and flagella is connected to the cell by modified centriole structures called basal bodies. Movement is produced when the nine paired microtubule sets of the axoneme slide against one another causing cilia and flagella to bend. The motor protein dynein is responsible for generating the force required for movement. WebRegulation of flagellar motility during biofilm formation Many bacteria swim in liquid or swarm over solid surfaces by synthesizing rotary flagella. The same bacteria that are motile also commonly form nonmotile multicellular aggregates called biofilms. WebJul 18, 2024 · Flagella (singular: flagellum) are long, thin, complementary whips attached to bacterial cells that allow bacterial movement (motility).
