To what taxon group (at the most specific level covered in lecture) are mitochondria most closely related to at the genetic level?
  • ameobozoans
  • Proteobacteria
  • cyanobacteria
  • seed dispersers
Describe four lines of evidence that support the endosymbiotic hypothesis ofmitochondrial origin in eukaryotes. Be
  • Angiosperm
  • Can achieve a smaller size
  • Larvae use notochords to organize their nervous systems; adults' nervous systems are more locally distributed.
  • Any of the following:Double-membrane of mitochondria: result of engulfment of the bacteria by theeukaryotic ancestor.Separate DNA in mitochondria: supports idea of bacterial ancestor with its own DNACircular mitochondrial DNA: bacteria also have circular DNAMitochondria have their own ribosomes that resemble bacterial ribosomes thaneukaryote ribosomes.Mitochondria divide independently of the cell, just as the bacterial ancestor would divideindependently.Mitochondrial dna is more closely related to bacterial dna than it is to eukayote DNA,indicating a more recent common ancestor for mitochondria and bacteria thanmitochodria and eukarya.Mitochondria are a similar size as bacteria.
