What is endosymbiont theory and how does it explain the origin of eukaryotes?

Back

It is a theory that explains the origins of cellular organelles in eukaryotic cells as originating from one cell becoming incorporated inside another.

Front

Which of the following is NOT a eukaryote?
1. Turdus maximus, a species of bird (animal) from Asia
2. Amanita virosa, one of the deadliest mushroom (fungus) species to humans
3. Brassica oleracea, perhaps the most widely domesticated plant known; cabbage, broccoli, cauliflower, Brussels sprouts, Kohlrabi, and kale are all varieties of this plant species
4. Staphylococcus aureus, a common bacterial species found worldwide that causes most staph infections in humans and now contains various antibiotic-resistant strains
5. Plasmodium falciparum, a protist species vectored by mosquitoes that remains the #1 killer of humans in the tropics

Front

There are currently----- supergroups recognized within the eukaryotes, and all of the eukaryotes, including all protists, animals, plants, and fungi fit into one of these.

Front

Several lines of evidence suggest that mitochondria and chloroplasts were once their own prokaryotic organisms and became part of eukaryotic cells by endosymbiosis. Which of the following lines of evidence are examples of these? Mitochondria and chloroplasts each have their own DNA that is independent of the nuclear DNA of the host cell. The DNA of chloroplasts is very similar to that of cyanobacteria. The DNA of mitochondria is very similar to that of purple bacteria.
