Document Summary
Structure found in core of eukaryotic flagellum (axoneme) Consists of: 9 fused pains of microtubule doublets on outside, central microtubule, the base of the flagellum, basal body. Inner and outer dyenein arms that are responsible for the flagellar beating and connect doublets. One of the major components in microfilaments and the cytoskeleton. Functions: cell mobility (with myosin motors, cell division and cytokinesis (with myosin motors, vesicle and organelle movement i. e. skeleton, muscle contraction. How amoebozoa change their shape, along with myosin motors. This group contains amoebas and other protozoans that move by using their mobile extensions of the cytoplasm called pseudopodia (usually finger-like, large, and blunt looking). Nutrition in most forms is attained by phagocytosis. Endoplasm is converted to ectoplasm at the front of the amoeba. Amoebae move by the flowing of their cytoplasm over the surface of the mud or soil.
