Cilia and flagella are small structures attached to eukaryotic and prokaryotic cells. These structures help in the movement of unicellular organisms. The chief difference between cilia and flagella is that the flagella are long and appear in one to eight per cell. The cilia are short and abundant in hundreds per cell. There are three major parts to the flagella, which includes the basal body, hook, and filament. Cilia are made up of small hair-like projections on the cell exterior.
Flagella are whip-like unbranched annexes that grow from the cell body. Many cilia are present in one cell, while flagella only come a few in a cell. Cilia beat in coordinated rhythms, while flagella beat independently.
