Introduction The purpose of this lecture is to introduce you to terminology used in microbiology. Microorganisms can be classified on the basis of cell structure, cellular metabolism, or on differences in cell components such as DNA, fatty acids, pigments, antigens, and quinones. Bacterial Morphology: Basic morphological differences between bacteria. Recent advances in biochemical and electron microscopic techniques, as well as in testing that investigates the genetic relatedness among species, have redefined previously established taxonomic relationships and have fortified support for a five-kingdom classification of living organisms.

Microscopic organisms, commonly known as microorganisms or microbes, are found all around us and even inside our bodies. In biology, the field of taxonomy is tasked with describing, naming, and classifying organisms; the latter according to some metrics of similarity.

Microorganisms are a heterogeneous group of several distinct classes of living. Different from parasites and fungi (eukaryotic) •Prokaryotic organisms –simple unicellular organisms –no nuclear membrane –no mitochondria –no Golgi bodies –no endoplastic reticulum •Complex cell wall –Gram-positive –Gram-negative. Unit 13 Classification of Organisms I. Classification of Fungi. 2. In News & Views 0. Introduction. Because of this character, they contribute greatly to humans and the environment. Gram-negative bacteria are more resistant against antibodies because their cell wall is impenetrable. Meaning and Characters of Cyanobacteria: The cyanobacteria (the earlier blue-green algae), or the blue-green bacteria, represent a group of photosynthetic, mostly photolysis-mediated oxygen-evolving monerans (prokaryotes).
