A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
Although protist flagella have a diversity of forms and functions, [11] two large families, flagellates and ciliates, can be distinguished by the shape and beating pattern of their flagella. [ 2 ] In the phylogenetic tree on the right, aquatic organisms (living in marine, brackish, or freshwater environments) have their branches drawn in blue ...
Bacterial flagella are helical filaments, each with a rotary motor at its base which can turn clockwise or counterclockwise. [16] [17] [18] They provide two of several kinds of bacterial motility. [19] [20] Archaeal flagella are called archaella, and function in much the same way as bacterial flagella
[2]: 396 The bacterial flagellum is the best known example. [27] [28] About half of all known bacteria have at least one flagellum; thus, given the ubiquity of bacteria, rotation may in fact be the most common form of locomotion used by living systems—though its use is restricted to the microscopic environment. [29]
By cooperatively moving their flagella, choanocytes filter particles out of the water and into the spongocoel, and out through the osculum.This improves both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products.

Movement of the flagellum draws water through the collar, and bacteria and detritus are captured by the microvilli and ingested. [12] Water currents generated by the flagellum also push free-swimming cells along, as in animal sperm. In contrast, most other flagellates are pulled by their flagella. [citation needed]
