Carolus linnaes developed classification scheme; he arranged organisms into ascending groups of increasing inclusiveness and tries to represent evolutionary history and interrelatedness. Domain and also binomial nomenclature- genus and species. 3 shapes- coccus, spirillum, bacillus and based on cell wall gram positive thick peptidoglycan. retaines crystal violet gram negative thin peptidoglycan, lps, antibiotic resistant, retains safranin main differences between prokaryotic and eukaryotic. Prokaryotic: unicellular, single circular chromosomes, asexual binary fission, no compartmentalization, no mitochondria, no nucleus- nucleoid region instead, peptidoglycan cell wall. Eukaryotic: multicellular, linear chromosomes, mitosis, compartementilization, mitochondria, nuclues, absent cell wall in animals biochemical characteristics of bacteria. 1. whether or not they can use oxygen for cellular respiration (anaerobic, aerobic)
