The unit begins with the idea of organisms which cannot be seen through our naked eyes. We then look at how those organisms can be seen.after a brief discription of earlier microbiologists and their contribution to the field of microbiology. Further this topic can be eloborated by identifying permanent slides of microbes in the microscope, and then classify the same based on the shape, structure and mode of nutrition. The unit extends as by listing out the uses of microorganisms in the day today life, industry, in the field of medicine, microbes in the kitchen etc.along with that discuss the harmful effects of microbes.
