Flagella shape derives the bacteria swimming

WebCiliates are generally ovoid or pear-shaped and maintain their shape by means of a tough but flexible pellicle. Cilia protrude through the pellicle in a variety of patterns. The term ciliate comes from the Latin word “ciliate” which means eyelash. Free-swimming ciliates range in size from 40-100 micrometers. WebCells of swimming Synechococcus are coccoid to rod-shaped and range in size from 0.7 to 0.9 µm in diameter and 1 to 2.5 µm in length (Waterbury et al., 1985). Certain features of swimming in Synechococcus resemble flagellar swimming. Swimming speeds range from 5 to 25 µm/sec (Waterbury et al., 1985; Willey, 1988). Swimming cells
