Which of the following can NOT be part of a prokaryotic cell?

• cell membrane

• cell wall

• genetic material (DNA)

• nucleus

There are more bacteria on you than there are of your own cells. There are also more bacteria on this earth than eukaryotic cells. In relation to cell complexity why might that be?

• prokaryotes are simpler and able basically can survive every where. Even places you might not think life could be found.

• Prokaryotes are more complex and only able to survive in very strict environments.

____________ & _________________ are organelles that definitely arose from endosymbiosis.

• Nucleus and cell membrane

• Chloroplast and mitochondria

• Mitochondria and nucleus

• Cell wall and chloroplast

The theory of Endosymbiosis explains

• The origin of eukaryotes

• How bacteria live

• How species develop

• Why cells rely on one another

The endosymbiotic theory states that a prokaryotic cell...

• grew out of an aerobic prokaryotic cell

• engulfed an aerobic bacteria and photosynthetic bacteria

• grew out of a photosynthetic prokaryotic cell

• digested an aerobic bacteria and photosynthetic bacteria
