BIOL 2051 Chapter : Structure And Function Study Questions 1
Document Summary
What type of microscopy did he use: robert hooke, first to look at cork under a microscope and first to apply the word cell because of the individual compartments to help describe the basic unit of life. Describe what that value means in practical terms when viewing a specimen: ~. 2microns (um), but it will be tiny; the smallest cells you"ll be able to see in lab is e coli. Would this cell have a high or low surface area-to-volume ratio compared to an average eukaryotic cell: would have a high sa to vol ratio- If gram positive or negative: negative- few layers (<10% of wall, positive- several layers (90% of wall, describe the peptidoglycan structure, repeating structure of n-acetyleglucosamine and n-acetylemuramic acid with a tetrapeptide crosslink which holds the peptidoglycan together. If a solute that does not penetrate the cells is added to a cell suspension containing lysozyme, the solute concentration outside the cell balances the concentration inside (isotonic).
