secretory vesicles, chromosomes during cell division and of specialized cell projections such as cilia and flagella. D. Organelles – specialized structures within the cell that have characteristic shapes and they perform specific functions in cellular growth, maintenance and reproduction. I. Centrosome – located near the nucleus and consists of two components: a pair of centrioles and pericentriolar material. They replicate during cell division so that succeeding generations of cells have the capacity for cell division a. Centriole – cylindrical structures which are composed of nine clusters of three microtubules arranged in a circular pattern. b. pericentriolar material – surrounds the centrioles and contains tubulins that build microtubules in non-dividing cells; also forms mitotic spindle during cell division. c. Tubulin – these are the organizing centers for growth of the mitotic spindle which plays a critical role in cell division and for microtubule formation in nondividing cells. II. cilium (plural is cilia) – numerous, short, hair-like projections that extend from the surface of the cell. They help move fluids along a cell’s surface. i.e. cells in respiratory tract have hundreds of cilia that sweep away
