Prokaryotes – Chapter 27 Prevalence of Prokaryotes 2 Groups Interesting facts Prokaryote Structure Capsule Cytoplasm Cell wall DNA Pili Flagellum Plasma membrane ribosomes size? DNA? plasma membrane? external features? Prokaryotic form: three shapes. Which form colonies? Pictures? Types of prokaryotes Coccus (5 types) Bacillus (2 types) Spiral (3 types) Prokaryotes versus Eukaryotes unicellularity cell size chromosomes cell division and recombination internal compartmentalization flagella metabolic diversity prokaryotic classification 2 methods old vs. new 2 branches of prokaryotes. Which one is actually older? Comparing archaebacteria and bacteria plasma membranes cell wall gene translation machinery (What does this mean?) gene architecture Prokaryotic cell surface peptidoglycan why is it important? Gram positive vs. Gram negative Prokaryote Cell Interior Internal membranes Nucleoid region plasmids: Ribosomes Do you think that it is likely that photosynthetic and respiratory membranes evolved more than once? How could your idea be tested experimentally? Processes to Create Prokaryotic Variation mutation How do antibiotic resistant bacteria arise? Why could antibiotic soaps be a problem? Why should you take all 10 days of your medication? What is the process behind this experiment? genetic recombination conjugation: Prokaryotic Metabolism Autotroph vs. Heterotroph Chemotroph vs phototroph What role to nitrifiers play in the environment? Classroom?
