Bacteria Flashcards
Eu bacteria
aerobic, prokaryotic cell, most bacteria, have membrane bound organelles
Pro bacteria
no nucleus or membrane bound organelles cell membrane, cell walls (carbs+proteins), Cytoplasm, Ribosomes, DNA, Plasmids
Autotrophic
make their own food
Heterotrophic
Cannot produce their own food, feed on dead organisms. (Pathogens)
Photoautotroph
energy from sunlight
Chemoautotroph
energy from inorganic sources (Archea)
Plasmid
extra loop of DNA
Endospore
bacteria survive harsh conditions by forming endospores
Bacillus
rod shaped
Coccus
Sphere
Spirillium
spiral
Strepto
Chain
Staphlo
cluster
Obligate aerobes
must have oxygen
Faculative anaerobes
can live or without oxygen
Obligate anaerobes
live only without oxygen
Binary Fission
asexual reproduction, every 20 minutes
Conjugation
Bacterial resistance to antibiotics gene may be passed
Transduction
bacteriophage (Virus that kills cells) injects DNA into cells
Transformation
DNA is released from a dead cell it can be absorbed by a living cell (endocytosis)
Exponential graph
higher birth rate
Stationary graph
equal birth and death rates
Death Graph
Higher death rate
Gram Positive
Purple, thick walls but big holes in it, easier to kill
