- 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
