BIOL 2051 Chapter : Structure And Function Study Questions
Document Summary
Structure & function: name 6 abilities of living cells. He drew his observations of what appear to be bacteria. Describe what that value means in practical terms when viewing a specimen. It aids in nutrient exchange with the environment and riddance of waste products. Size also affects physiology, growth rate and ecology: discuss the problems a cell might have it were less than 0. 2microns. It would be difficult to contain all the necessary molecules and organelles to function as a free-living cell: compare and contrast a prokaryotic microbial cell and eukaryotic microbial cell. Both have- dna, cytoplasmic membrane, cytoplasm, ribosomes and can have cell wall. Bacteria- fatty acids attached to glycerophosphates with ester linkages, hopanoids(diploptene) help strengthen. Eukarya- fatty acids attached to glycerophosphates with ester linkages, sterols(cholesterol) help strengthen. Archaea- phytanyl attached to glycerophosphates with ether linkages. Permeability layer- prevents leakage and functions as a gateway for transport of nutrients and waste.
