Phylogenetic Tree
A branching diagram that represents a hypothesis of the evolutionary history of a group of organisms.
Three Origins of Life
Eukarya
Archaea
Bacteria
Endosymbiosis Theory
That a eukaryotic cell engulfed a non photosythetic aerobic bacterium, forming an endosybiont mitochondrion.
And that a eukaryotic cell engulfed a prokaryotic cell that could carry out photosythesis, forming an endosymbiont chloroplast.
Cell With Nuclear Envelope
Eukaryote
Cell with Membrane Enclosed Organelles
Eukaryote
Cell with Peptidoglycan in the Cell Wall
Bacteria
Cell’s with Circular Chromosomes
Archaea and Bacteria
Cell which grows in >100 degrees celcius
Some Archaea
Peptidoglycan
A polymer consisting of modified sugars cross linked by polypeptides found in the cell wall of bacteria
Do Prokaryotes or Eukaryotes have a Nucleus?
Eukaryotes have a nucleus, prokaryotes do not
