Endosymbiosis

Start by brain-dumping your understanding of #017 here. DESCRIBE the diagram from the Classkick that was labeled 'endosymbiosis', then EXPLAIN your understanding of that diagram. INCLUDE and APPLY the other information from #017; how do bacterial, plant, and animal cells 'fit in' to endosymbiosis based on their features?

You should use TERMS and DIRECT REFERENCES to #017 to build your answer, NOT Google. An inaccurate answer is fine, because it'll set a foundation for you to correct against using the video. You should do as complete an answer as possible; it'll take around 3 sentences, min., to DESCRIBE Endosymbiosis, probably another 2-5 to EXPLAIN what you know so far about endosymbiosis to begin with, and then 3-6 or so to incorporate the other material from #017. You may finish with an answer from 8-13 sentences, easy!

This is a rare assignment where I say you probably want to note-take. You can note-take directly on #017 if you want, on the page appropriate, or you can work on paper. Focus on DRAWING things and labeling them- don't try to write a visual process out verbatim.

• I can and probably should take notes here!

• Metcalf still recommends not to take notes.

I used this video because it has many redeeming qualities. However, there is one MAJOR conceptual error in the animation. You need to identify it by comparing the diagram here and the animation as it proceeded up until this point (you can rewind!) Check with me directly before proceeding. 

I highly, highly, highly suggest DRAWING and labeling (by paraphrasing) the diagram below in your notes.  It's why I didn't ask you many questions: so you'd have time to DRAW AND LABEL.

Do as he said and think about the membranes surrounding the engulfed soon-to-be-organelles on the left. Which of the following would be good evidence that they had been engulfed?

• One phospholipid bilayer membrane, resembling a prokaryote membrane

• Two phospholipid bilayer membranes, the inner membrane resembling a prokaryote membrane, the external membrane resembling a modern eukaryote membrane

• Two phospholipid bilayer membranes, the inner membrane resembling a modern eukaryote membrane, the external membrane resembling a prokaryote membrane

• One phospholipid bilayer membrane, resembling a modern eukaryote membrane

Algae are eukaryotes. If euglena engulfed an algae, describe what you would expect to see surrounding the engulfed algae (consider the previous evidence).

How has your understanding of endosymbiosis CHANGED from your first introduction to it in #017? EXPLAIN any changes in your undestanding and PROPOSE any lingering questions, whether or not you believe your questions are related.
