Each centriole is composed of 9 microtubule triplets. 1 of 20 Centrosome and centriole function Movement of chromosomes during cell division and organisation of microtubules in cytoskeleton. 2 of 20 Cytoskeleton structure Proteins organised in fine filaments or slender tubes 3 of 20 Cytoskeleton function Strength and support. Movement of cellular structures and materials. 4 of 20 Plasma membrane structure Lipid bilayer containing phospholipids, steroids, proteins and carbohydrates 5 of 20 Plasma membrane functions (5) Isolation, protection, sensitivity, support, control entry and exit of materials 6 of 20 Microvilli structure and function Membrane extensions containing microfilaments. Increase surface area for absorption 7 of 20 Cilia structure and function Long extensions containing microtubule doublets in a 9+2 array. Movement of material over cell surface. 8 of 20 Proteasomes structure and function Hollow cylinders of proteolytic enzymes with regulatory proteins at their ends. Breakdown and recycling of damaged or abnormal intracellular proteins. 9 of 20 Ribosomes RNA and proteins. Protein synthesis 10 of 20 Peroxisomes Vesicles containing degredative enzymes. Catabolism of fats and organic compounds, neutralisation of toxic compounds generated in the process. 11 of 20 Lysosomes Vesicles conating digestive enzymes. Intracellular removsl of damaged organelles or pathogens. 12 of 20 Golgi apparatus Stacks of flattened membranes containing chambers. Storage, alteration and packaging of secretory products and lysosomal enzymes. 13 of 20 Mitochondria Double membrane with inner membrane folds enclosing important metabolic enzymes. Production of ATP. 14 of 20 Endoplasmic reticulum (ER) Network of membranous channels extending throughout the cytoplasm. Synthesis of secretory products and inracellular storage and tranport. 15 of 20 Nucleus structure Nucleoplasm containing nucleotides, enzymes, nucleoproteins and chromatin. Surrounded by a double membrane nuclear envelope. 16 of 20 Nucleus function Control of metabolism, storage and processing of genetic information and control of protein synthesis. 17 of 20 Nucleolus Site of RNA synthesis and assembly of ribosomal subunits 18 of 20 Rough ER Protein synthesis 19 of 20 Smooth ER Synthesises and secretes lipids and steroids 20 of 20
