4.Describe the structure and functions of cytoplasm, its cytosol, and the organelles listedbelow.
secretory vesicles, chromosomes during cell division and of specialized cellprojections such as cilia and flagella.D.Organelles – specialized structures within the cell that have characteristic shapesand they perform specific functions in cellular growth, maintenance andreproduction.I.Centrosome – located near the nucleus and consists of two components: apair of centrioles and pericentriolar material. They replicate during celldivision so that succeeding generations of cells have the capacity for celldivisiona.Centriole – cylindrical structures which are composed of nineclusters of three microtubules arranged in a circular pattern.b.pericentriolar material – surrounds the centrioles and containstubulins that build microtubules in non-dividing cells; also formsmitotic spindle during cell division.c.Tubulin – these are the organizing centers for growth of the mitoticspindle which plays a critical role in cell division and formicrotubule formation in nondividing cells.II.cilium (plural is cilia) – numerous, short, hair-like projections that extendfrom 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
