WebSep 14, 2024 · Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles. When did mitochondria and chloroplasts evolve? Summary. Eukaryotic cells probably evolved about 2 billion years ago. Their evolution is explained by endosymbiotic theory. WebApr 10, 2024 · Eukaryotes such as fungi and protists frequently accompany bacteria and archaea in microbial communities. Unfortunately, their presence is difficult to study with “shotgun” metagenomic sequencing since prokaryotic signals dominate in most environments.
