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.
The algal body consists of green, un-branched, ... Each zoospore has a small hyaline anterior region, and at the base of this region is a ring of flagella (~150 ...
Schematic drawing of Cafeteria roenbergensis (Heterokonta: Bicosoecida) with two unequal (heterokont) flagella: an anterior straminipilous (with tubular tripartite mastigonemes) and a posterior smooth A chrysomonad (Heterokonta: Chrysophyceae) under TEM, with a smooth flagellum (1) and a long flagellum covered with mastigonemes (3) Two cryptomonads (Cryptophyceae) under SEM.
The Oedogoniales are an order of filamentous freshwater green algae of the class Chlorophyceae. [1] The order is well-defined and has several unique features, including asexual reproduction with zoospores that possess stephanokont flagella: numerous short flagella arranged in a subapical whorl. [1]
The cell contains a pellicle which is a flexible outer covering made up of proteinaceous strips called pellicular strips. This pellicle provides shape and structure to the cell. The movement of the E. gracilis is primarily achieved by its flagellum that emerges from a flagellar pocket. It has forward and backwards movement, as well as changes ...
The longitudinal flagellum is relatively conventional in appearance, with few or no hairs. It beats with only one or two periods to its wave. The flagella lie in surface grooves: the transverse one in the cingulum and the longitudinal one in the sulcus, although its distal portion projects freely behind the cell.
Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
Flagella in eukaryotes are supported by microtubules in a characteristic arrangement, with nine fused pairs surrounding two central singlets. These arise from a basal body. In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella role in classifying eukaryotes.
