Prokaryotes
Archaebacteria and Eubacteria
How are they the same?
cell wall
circular loop
very small!! 9 milimeters
used to both be in monera
Archaebacteria
live in harsh envioronments
(hotsprings, digestive tracts, salty water)
Eubacteria
peptoglycan in cell wall
share many genes with eukaryotes
Bacilli
rod shaped
cocci
ball shaped
spirilla
spiral shaped
cilia
hairs that swim
falagella
tails that whip
autotrophic
feed themselves (photosynthesis or chemosynthesis
heterotrophs
decomposers eating decaying organic matter
when bacteris split into two copies of themselves
binary fission
during which bacteria may exchange genetic information
conjugation
when conditions are bad DNA is placed here to protect it until it can germenate
endospores
helped with classification system?
carlous Linnaeus
a swedish botanist
structural similarities reflect?
evolutionary similarities
binomial nomenclature
developed by Linnaeus
written in latin
2 words
What does King Phillip Came Over For Good Spices represent?
Kingdom, Phylum, Class, Order, FAmily, Genus, Spices
What do phylogeny and caledistics do?
show the evolutionary history of a species
phylogeny
it assumes that organisms diverge from a common ancesteral group
cladogram
a model of the phylogeny of a species
dichotmus key
identifies an organism based on certain characteristics
Charles Darwin
sails on HMS beagle to galapogos
catalyst to evolutionary theory
Natural Selection
mechanism for change in a species over time (those who are fit survive and reproduce)
Structural Adaptation
developes over many generations (a thorn, a porcupine..etc) can be seen
Physiological adaptation
happens rapidly
like a chemical change, not always seen
Indirect evidence for evolution
fossils, embryology, anatomy, biochemistry
Analougous structures
similar in function but not in appearence
Homolougous
same structure different function
Adaptive radiation
one species evolves into sever subspecies
Divergent
one ancesteral species evolves into several very different species
convergent
distantly related organisms evolve into similar species
gene pool
alleles of population genes brought together
allelic frequency
percentage of any specific allele in gene pool
genetic equilibrium
alleles remain the same
gene flow
transport of genes by migrants
genetic drift
the amish ppl
