Week 3 discussion

Please watch the videos found at https://www.youtube.com/watch?v=gFuEo2ccTPA and https://www.youtube.com/watch?v=URUJD5NEXC8. You will need to go to YouTube to watch the second video, as its author has restricted the ability to embed it in other content. That video provides an introduction to terminology used to describe cell types and cell components, and different types of cells:

Even though the basic composition of most cells are similar, there are many different types of specialized cells found as single-cell organisms and in in various multi-cell organisms.

In your main post for this discussion you are to describe the theory of endosymbiosis as proposed by Lynn Margulis; (1) describe the theory in general terms; (2) describe what chloroplasts and mitochondria produce in eukaryotic cells (the specific chemical that is produced by electron transport systems in both cases), (3) provide three details from cell biology that support the theory.

You main response should be at least 150 words and include references to all information sources used.

You also need to post at least two 150+ word replies to the posts of other students. Ask thought-provoking questions and/or provide additional information.
