what do cilia or flagella do ?
Both cilia and flagella function in movement. They may either move the cell or move something across the surface of the cell. Both may be used for movement or for feeding, depending on the organism. Cilia are short, hairlike projections and usually form long rows along some or all of a cell's suface. Flagella are long, whiplike projections and may be found alone or in small groups on the surface of some cells.
