Endosymbiotic Theory

Understand Endosymbiotic Theory! Learn how cells evolved with this interactive worksheet.

Sort the definition with the correct term. Use the video for help! Cell basic unit of life Endosymbiosis ecological relationship in which one organism lives within the body of another Eukaryote cell that has a nucleus and contains membrane-bound organelles Prokaryote cell that does not have a nucleus or membrane-bound organelles Answer the questions below as they are mentioned in the Amoeba Sisters video. You might want to open the video in a separate tab. You will have to rewind and pause since the questions are scattered throughout the video. The endosymbiotic theory gives an explanation for how eukaryotic cells could have evolved from prokaryotic cells that lived in symbiosis (lived together). It is thought that chloroplasts evolved from photosynthetic bacteria and mitochondria evolved from bacteria that used oxygen to make energy and were engulfed by larger bacteria, but not consumed.--Prokaryote vs. Eukaryote--Prokaryotes have no nucleus. So the saying goes "Pro - No"Eukaryotes have a nucleus. So the saying goes "You - Do" Identify whether the statement is true or false. Click on each statement and sort it into the correct "true" or "false" category. True cells that have chloroplasts also have a mitochondria eukaryotes came from prokaryotes all eukaryotic cells have a mitochodria mitochondria were thought to have come before chloroplasts mitochondria and chloroplasts have their own DNA that is separate from the nucleus False mitochondria and chloroplast DNA are the same chloroplast DNA is the same as the nucleus prokaryotes came from eukaryotes all eukaryotic cells have chloroplasts chloroplasts were thought to have come before mitochondria
