How much you enlarge something. 2 of 29 magnification of light microscope? 1500 3 of 29 magnification of a transmission electron microscope? 500,000 4 of 29 magnification of scanning electronmicroscope? 100,000 5 of 29 What is staining? A process that helps reveal or distinguish different features 6 of 29 What is sectioning? When specimens are embedded in wax so thin sections can be cut without distorting the stucture of the specimen. 7 of 29 What is the 2 types of cells? prokaryotic and eukaryotic. 8 of 29 What is the difference between prokaryotic and eukaryotic? pro- no nucleus, no membrane bound organelles Eu- nucleus, membrane bound organelles 9 of 29 What is the function of the cytoskelton? Its a network of protein fiaments running through the c 10 of 29 What is the cytoskelton made up of? microtubules, microfilaments and intermediate filaments 11 of 29 Why do cells need membranes? separte cell components from outside environment and cytoplasm. 12 of 29 what is the plasma membrane made up of? phospholipids 13 of 29 what transport processes take place in the plasma membrane? substances move passively ( without energy) such as diffusio. some move actively (uses energy) such as active transport. 14 of 29 what metabolic processes take place in the plasma membrane membranes contain enzymes. These enzymes catalyse some of the final stages in the breakdown of some types of sugar. 15 of 29 what communication processes take place in the plasma membrane receptors in the cells plasma membrane picks up signals and brings about actions within the cell know as cell signalling. 16 of 29 What are the key components of the membrane? cholesterol, glycoproteins, glycolipids, phospholipids, proteins 17 of 29 function of chloroplasts? site of photosynthesis 18 of 29 function of cell wall? add protection and support 19 of 29 function of lysosomes? contain digestive enzymes to digest unwanted particles 20 of 29 function of centrioles? take part in cell division 21 of 29 function of cillia and flagella? cillia- waft mucus up throat flagella - moving stuff around 22 of 29 function of vesicles and vacuoles? stores of water,food or waste materials 23 of 29 function of nucleus? controls the cell 24 of 29 function of ribosomes? where proteins are synthesised 25 of 29 function of cell surface membrane? defines perimeter 26 of 29 function of mitochondria? powerhouse of the cell 27 of 29 function ofgolgi body? process, package and distribute molecules 28 of 29 function of endoplasmic reticulum? collection, storage and distribution 29 of 29
