Directions: The mitochondria and chloroplast are thought to have once been free-living prokaryotes that were engulfed by an early eukaryote and incorporated into the functioning of that cell. For this discussion, describe the theory of endosymbiosis in your own words and discuss some of the evidence for this theory. You can use your textbook as a reference and research this theory online as well. For full credit, I will be looking for unique thoughts (compared to other classmate submissions) on the evidence for the theory of endosymbiosis and your interaction with classmates.

Submission: After you have posted your initial post, read and respond to two or more of your classmates' posts. Be sure to make substantive and constructive comments (just posting “nice post” doesn’t count). For example, add something from your own experience, something you’ve read or seen. If the situation calls for it, feel free to state an opinion, but be sure to state any points with which you agree and/or those with which you disagree, as well as your reasons for agreeing or disagreeing.
