WebEukaryotes emerged approximately 2.1–1.6 billion years ago, during the Proterozoic eon, likely as flagellated phagotrophs.[13] Eukaryotic cells typically contain other membrane-bound organelles such as mitochondria and Golgi apparatus; and chloroplasts can be found in plants and algae. Prokaryotic cells may contain primitive organelles.[14] WebHaplosporidia. The haplosporidians are a small group of parasites of aquatic invertebrates, notably marine mollusks, and the parabasalans (anaerobic flagellates with hydrogenosomes, e.g., Trichomonas) are all parasites, with one or two possible exceptions (Pseudotrichomonas).
