Microbiology Slides Bio 104 Practical The Structure of the Prokaryote Cell • Small size ( 0.5 to 2um) • Large surface area to volume ratio • A variety of shapes • Outer cell wall- very thick made of specialized molecules • Cell membranes may have a different constituency of molecules from eukaryote cells • Ribosomes smaller • No organelles, no nuclear membrane •1 ds circular loop of DNA Shapes of the Bacteria • Bacillus • Coccus • Vibrio • Spirillum • Spirochete • Pleiomorphism- Some bacterial shapes vary within a culture. This can occur when the nutrients are used and wastes have built up Cell Morphology Arrangement of bacteria • Groups of two- diplo • Chains- strepto • Large groups- like grape clustersstaphylo • Division on 3 planes- sarcinae- 8 cells arranged in a cube • Division on two planes produces tetrads Bacterial Shapes Diplococcus Streptobacilli Spirillum Spirochetes Streptobacilli Streptococcus pyogenes- strep throat Staphylococcus Staphylococcus
