Cilia and Flagella: Structure, Function & 9+2 Arrangement (NEET Notes)

  Cilia vs Flagella: Easy NEET Biology Notes with Diagram & Mind Map  Structure of cilia and flagella showing the 9+2 microtubule arrangement and basal body in a eukaryotic cell. - Dr. Sanjay Kumar Pawar  Cilia and Flagella – Basic Idea Cilia and flagella are hair-like structures present on the surface of the cell. They are extensions of the cell membrane . Cilia Cilia are short and numerous hair-like structures . They move in a coordinated, oar-like motion (like rowing a boat). Function: Help in movement of the cell (e.g., Paramecium). Or move fluid/particles around the cell (e.g., in respiratory tract). Flagella Flagella are long, whip-like structures . Usually present in fewer numbers (1 or 2 per cell) . Function: Responsible for movement of the whole cell (e.g., sperm cell). Difference between Prokaryotic and Eukaryotic Flagella Prokaryotic flagella (bacteria) : Structurally different from eukaryotic flagella. Eukaryotic fla...
