time
what are the tree domains of life
Eukarya
archaea
Bacteria
what does the tree of life show
Show the relationship between the characteristics of all species.
how do you read a phylogenetic tree
Looking at an animal you can look back to the characteristics it has, this can be compaired to other animals and the number of shared characteristics
endosymbiosis theory states what
ansestors of eukariote engulphed oxygen using prokarioite. formed an endosymiant, evolved together. mitocondria eveolved first then chloroplast.
what is the diffrence between prokaryotes and Eukaryotes
Eukaryotes are membrain encolsed organells
prokaryotes are non-membrane enclosed nucleus
Archaea have what properties
Circular membrain
sometime reproduce at high temps
Eukarya have what properties
nuclear envelope
membrain encolsed organells
bacteria have what properties
Peptidoglycan in cell walls
circular chromosome
endosymbiosis theory: mitocondria evolved from what
proteobacteria
endosymbiosis theory: chloroplast evolved from what
cyanobacteria
