Document Summary
10:46 am: purple= things said in class, not on slides. Explain functions of cell envelope and surface components. Describe the contents of the cytoplasm including specialized structures. Prokaryotes differ from eukaryotes in size and simplicity most lack internal membrane systems. No membrane bound nucleus term prokaryotes is becoming blurred this text will use bacteria and archaea rather that prokaryotes this chapter will cover bacteria and their structures. Cocci (s. , coccus) spheres diplococci (s. , diplococcus) pairs streptococci chains streptococci chains staphylococci grape-like clusters tetrads 4 cocci in a square sarcinae cubic configuration of 8 cocci. There is a regulatory system that regulates these processes. Bacilli (s. , bacillus) rods coccobacilli very short rods. Pleomorphic organisms that are variable in shape. Small size may be protective mechanism from predation. The more compact and less elaborate, the higher the surface area/volume ratio. The more surface area/volume, the faster you can bring material in to that space.
