Evolution of Organelles

Click here to view an animation that explains the Endosymbiotic Theory. It's hard to believe that mitochondria and chloroplasts were once independent cells! What do you think?

  1. The animation is so cool, it showed how mitochondria and chloroplasts were similar to prokaryotes, and how the cell that absorbed it didn't digest it so it was a win-win situation

  2. How could a eukaryote digest a prokaryote yet not destroy it?
    The theory is really interesting, I think it makes sense.

  3. That is cool, but how did the organelles function?

  4. I think it's pretty darn amazing that we came to be humans out of prokaryotes. Obviously, this took thousands of millions of years, but it was still pretty cool to know that you came out of simple organelles.

  5. I think that it's really cool that Mitochondria and other organelles were once their own individual cells.

  6. This is very interesting, but what usually happened when a eukaryotic cell engulfed a prokaryotic cell? Did it just digest the prokaryotic cell?

  7. thanks so much for posting this animation i love all the animations because they allow you to visualize cell evolution that you would never get a clean look at in real life!

  8. Thanks Leslie, that was really interesting! This just shows how much some organelles have evolved over time.

  9. I really liked the animation! They were detailed and had a visual! Thanks Leslie!

  10. Rlly cool!!
    So the mitochondrion and chloroplasts were independent cells with their own DNA and could reproduce like prokaryotic cells but were engulfed by other cells, then forming a relationship???

  11. ohh...nevermind i think i get it!!!!!!!!!
    that would be soo cool if they actually evolved together!
    thanks for all the helpful links Leslie!

  12. This animation was so cool! I get that the mitochondria and chloroplasts were independent, but then another cell engulfed the mitochondria and chloroplast, but did not digest it... then over time, they became one. Thanks!

  13. I'm kindaa confused, so the eukaryote gave the prokaryote organic compounds, so that it could make ATP? what type of organic compounds, and was this possible for the eukaryote withoutthe prokaryote, like how did it make ATP without the prokaryote? Also, how does a eukaryote ingest a prokaryote?
    but overall pretty cool
    :)

  14. wow, i didn't know that organelles originated from prokaryotic cells that a eukaryotic cell engulfed. that's really cool!

  15. how did the organelles maintain homeostasis having no other organelles?

  16. intresting but it seems kind of unlikely. are there any other developing ideas?

  17. anyone ever notice haw the person speaking in these animation always sounds unnatural and unemotional. almost like a robot?

  18. The animation is really cool and fascinating. I had heard of the endosymbiotic theory before, but not like this. Thanx

  19. I loved the animation. Thanks Leslie.
    It helped me understand more about the topic

    Very interesting! I love it! So the older eukaryote cell( the big one) was probably anaerobic!

  21. It's really cool how humans, complex multi-cellular organisms, have evolved out of single celled organisms with organelles from billions of years ago. I think it's pretty amazing. Thanks for the animation, Leslie!

  22. so the prokaryote is being engulfed but not eaten?????

  23. cool, it's strange how our organelles used to be living organisms.

  24. That's really neat! I didn't know that they evolved over time, too!

  25. Fascinating as well as extremely coincidental. The complexity of organisms and their ancestors never cease to amaze me.
