→ Evolution of cells. Present-day cells evolved from a common prokaryotic ancestor along three lines of descent, giving rise to archaebacteria, eubacteria, and eukaryotes. Mitochondria and chloroplasts originated from the endosymbiotic association of aerobic family.New cells are formed from preexisting cells through mitosis. Sexually reproducing organisms also create a type of cell, called a gamete, through meiosis.
