Abstract

Cilia and flagella are hairlike cellular organelles for motility and are found in both the plant and animal kingdoms. Flagella are few in number, long and usually show an undulant motion, while cilia are more numerous, relatively short and show a pendular, often coordinated, stroke. According to Fawcett (1961), in plants flagella are found in the zoospores and gametes of some algae and aquatic fungi, and in spermatozoids of mosses, ferns, and two groups of primitive trees. In animals they are found in many protozoans, in most metazoan spermatozoa, and on several fixed-cell types such as sponge choanocytes, coelenterate gastroderm cells, and in certain cells of the nephron of vertebrates.
