Document Summary
Monophyletic group: all share a particular character, single phylogenic origin. Paraphyletic group: what"s left over after monophyletic group is removed, doesn"t tell you much. Do not form a natural group like plants, animals or fungi (protists are remaining eukaryotes) Endosymbiosis evolution of the endomembrane system may have allowed the enlargement of cell size developed from protrusions of the nuclear envelope, to which it still remains attached. Process by which mitochondria and plastids of eukaryotes arose. They divide before the rest of the cell by ssion, just like bacteria. Plastids were reminiscent of cyanobacterial cells living inside plant cells. Circular chromosomes of plastids and mitochondria are considerably smaller than those of. Bacteria, plastids and mitochondria all have a circular genome. Plastids and mitochondria contain small, bacterial sized ribosomes that translate their own their bacterial counterparts proteins from they genome. Organelle genes group wiht bacteria and no with own nuclei in eukaryotes.
