Cilia and Flagella: Structure & Function — NEET Biology
📚 Practice Concept📖 NCERT Source
Cilia (sing.: cilium) and flagella (sing.: flagellum) are hair-like outgrowths of the cell membrane. Cilia are small structures which work like oars, causing the movement of either the cell or the surrounding fluid. Flagella are comparatively longer and responsible for cell movement. The prokaryotic bacteria also possess flagella but these are structurally different from that of the eukaryotic flagella.

Assertion (A): Cilia enable cellular movement and fluid movement around cells. Reason (R): Cilia work like propellers through rotational motion to generate movement.
