Prokaryotic (no nucleus), circular DNA, does not go thru meiosis/mitosis, not haploid/diploid, reproduction by binary fission, smallest life form, ancient life form, extreme habitat diversity
Kingdom Plantae
Kingdom Monera
Kingdom Animalia
Life from Kingdom Monera reproduce by binary fission.
Cell wall of eubacteria is composed of:
chitin
peptidoglycen
cellulose
An ENDOSPORE is a swelling in the middle or end of a cell that allows it to survive extreme conditions. Some endospores produce deadly toxins and new cells.
BOTULISM means it cannot be killed by normal boiling.
The steps of gram staining include:
1. samples stained with crystal violet dye and iodine
2. samples are rinsed with alcohol
3. samples are stained with red dye
Gram positive-purple stains mean
simpler cell walls AND large amounts of peptidoglycan
structurally more complex AND less amounts of peptidoglycan
Gram negative-pink stains mean
simpler cell walls and large amounts of peptidoglycan
more complex cell walls and less peptidoglycan
CYANOBACTERIA
cells walls made of peptidoglycan
much larger than eubacteria
phycobilins aka photosynthetic accessories
Examples of cyanobacteria include Nostac and Oscillataria.
ARCHAEBACTERIA...
some have simple photosynthesis with no O2 byprdouct
cell wall types vary (carbohydrate, protein)
unique plasma membrane
extreme hostile habitats
Methanogens are a type of bacteria that produce methane gas. They are obligate . is methane bacteria that contributes to the 30% of methane gas in the atmosphere.
Extreme halophiles are salt loving.
Extreme halophiles are salt loving and are obligate .
Extreme thermophiles are heat loving and obligate anarobes.
Nostac is a -fixing bacteria. It has a special cell called a heterocyte that fixes the element while other cells photosynthesize.
Eubacteria that can fix nitrogen live in root nodules of legume plants.
Mutualism Commensalism Parasitism( Mutualism, Commensalism, Parasitism ) is where both organisms benefit. Commensalism Mutualism Parasitism( Commensalism, Mutualism, Parasitism ) is where one organism benefits and the other is unaffected. Parasitism Mutualism Commensalism( Parasitism, Mutualism, Commensalism ) is when one organism benefits while the other is harmed.
The site of photosynthesis is the chloroplast.
The mitochondria organelle is the site for respiration.
