Microbiology - ANSWER study of microbes
List groups of organisms studied in microbiology: - ANSWER bacteria, fungus,
algae/protists, viruses, helminthes
Differences between Prokaryotic and Eukaryotic cells: - ANSWER Prokaryotic
-no nucleus
-no membrane bound organelles
Eukaryotic
-true nucleus
-has membrane bound organelles
Animalae - ANSWER are not green, move
Evolution of microbial life on earth: - ANSWER No oxygen in early earthly era, bacteria
have been around as dominant life forms for a long time (3.5 billion years ago),
Endosymbiosis
Coccus - ANSWER circular shapes
Baccilus - ANSWER rod shaped
1
, Spirillum - ANSWER mutliple bends, appears spiral shaped
Diplo - ANSWER twos
Strepto - ANSWER chains
Staphylo - ANSWER clusters
Cytoplasm - ANSWER contains ribosomes, DNA - mixture of water, nutrients, proteins
Nucleoid - ANSWER acts as nucleus - contains DNA, RNA, proteins
Inclusion bodies - ANSWER granules for storage of extra carbon, nitrogen, phosphorus
- energy sources
Endospores - ANSWER DNA surrounded by proteins that protects central core of
bacteria, protects bacteria: resistant to heat, dessication, and chemicals
Cytoskeleton - ANSWER protein filaments assist with cell growth and division - binary
fission
Plasma membrane - ANSWER phospholipid bilayer with polar heads and hydrophilic
tails
Facilitated diffusion - ANSWER protein helps move molecules from higher
concentration to lower concentration
