NZQA registered unit standard 8024 version 5 Page 1 of 3 Title Demonstrate knowledge of bacterial structure Level 5 Credits 3 Purpose People credited with this unit standard are able to describe: the morphology and external structures of bacteria; the ultrastructure of bacteria; and the formation and function of bacterial endospores. Classification Science > Microbiology Available grade Achieved Explanatory notes Glossary Ultrastructure refers to the detailed structure of bacteria that can be observed by electron microscopy. It refers to the cellular structures that are too small to be seen with an optical microscope. Morphology refers to cell shape and cell arrangements. Outcomes and evidence requirements Outcome 1 Describe the morphology and external structures of bacteria. Evidence requirements 1.1 Bacteria groups are described in terms of morphology. Range 1.2 External structures are described in terms of their function. Range 1.3 cell wall, fimbriae, flagella, glycocalyx, pili. Gram positive and Gram negative bacteria walls are compared in terms of their chemical composition. Range 1.4 cocci, bacilli, spirillum. lipopolysaccharide, peptidoglycan, mycolic acid, teichoic acid. Gram positive and Gram negative bacteria walls are compared in terms of their physical composition.

Evidence requirements 2.1 The ultrastructure of bacteria is described in terms of the ultrastructure function. ultrastructure includes – bacterial chromosome, cytoplasmic membrane, inclusion granules, plasmids, periplasm, ribosomes. Range Outcome 3 Describe the formation and function of bacterial endospores. Evidence requirements 3.1 Factors are identified and the process described for the formation of bacterial endospores. 3.2 Endospore function is described in terms of its chemical and structural properties.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.
