Micro Revision by Adriela Jones https://padlet.com/adrielajones/nlhm6voycozr Characteristics of Microorganisms (Prokaryotes) en-us 2018-03-20 22:27:37 UTC 2018-03-29 07:46:55 UTC hello@padlet.com PROKARYOTIC MICROORGANISMS https://padlet.com/adrielajones/nlhm6voycozr/wish/244301110 Generally:
- cell wall
- cytoplasmic membrane
- ribosomes
- various inclusions (C, N, S, P etc)
- nucleoid (aggregation of DNA on one chromosome) — lack an organised nucleus and membrane bound organelles
- cell wall made of peptidoglycan]]> 2018-03-20 22:29:43 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244301110 Morphology adrielajones https://padlet.com/adrielajones/nlhm6voycozr/wish/244301221 coccus (round)
bacillus (rod-shaped)
spirillum (rigid spiral)
spirochete (corkscrew)
filamentous (wavy)
budding and appendaged bacteria - yeast only]]> 2018-03-20 22:30:31 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244301221 Size adrielajones https://padlet.com/adrielajones/nlhm6voycozr/wish/244302212 large surface area to volume area for exchange of nutrients and gas]]> 2018-03-20 22:36:29 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244302212 Motility https://padlet.com/adrielajones/nlhm6voycozr/wish/244302334 - generally through flagella
—> Can move when attracted to chemicals, gases, water, or light
- two kinds of movement
—> peritrichous or polar movement
- polar movement involves flagella at only one end of the prokaryote moving in one direction, while peritrichous movement has flagella all over the body of the organism
- peritrichous organisms can “tumble” and move in all directions]]> 2018-03-20 22:36:55 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244302334 Cell Wall adrielajones https://padlet.com/adrielajones/nlhm6voycozr/wish/244302394 gram positive
- thick, rough, large single layer of peptidoglycan
gram negative
- thin, smooth, multilayered membrane, small single layer peptidoglycan

peptidoglycan is only in bacteria

membrane is relatively weak and would rupture if it had to oppose pressure, therefore cell walls are necessary for shape and rigidity 

archaeal cell wall
- are different to bacteria cell wall
- relatively thick, possibly adaptation to extreme habitats
- composed of pseudopeptidoglycan, glycoproteins and proteins]]> 2018-03-20 22:37:17 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244302394 Sporulation chuyicy118 https://padlet.com/adrielajones/nlhm6voycozr/wish/244303513 Endospore  （resistant to

main differences
- size
- nuclear structure and function
- cytoplasmic structure and organisation
- possession of a cytoskeleton
- forms of motility]]> 2018-03-20 22:46:02 UTC https://padlet.com/adrielajones/nlhm6voycozr/wish/244303910
