Konstantin Mereschkowski's 1905 tree-of-life diagram, showing the origin of complex life-forms by two episodes of symbiogenesis, the incorporation of symbiotic bacteria to form successively nuclei and chloroplasts
Internal symbiont: mitochondrion has a matrix and membranes, like a free-living alphaproteobacterial cell, from which it may derive.
The eukaryotes are cellular organisms of the domain Eukaryota or Eukarya, which have a distinct cell nucleus, membrane-bound organelles and organization supported by a cytoskeleton. Extant eukaryotes
