Explore the endosymbiotic theory with the Amoeba Sisters! This theory explains the development of the eukaryote cell from prokaryote cell symbiosis. Scientific theories are also briefly defined. Expand details to see table of contents. 👇 This video has a handout here: http://www.amoebasisters.com/handouts...

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching biology at the high school level. For more information about The Amoeba Sisters, visit:

⭐We have a menu of our resources that complement our videos! Visit https://docs.google.com/spreadsheets/...

We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/bi...

We did want to note that there are different models for the potential host cell shown. This "early mitochondria" model shows a prokaryote - likely an Archaean - this is the model this video shows. However, other models can show a more complex proto-eukaryote or ancestor eukaryotic cell host. There is debate about the host cell based on these models. Some further reading suggestions that show these models: https://mbio.asm.org/content/11/3/e00... , https://www.ncbi.nlm.nih.gov/pmc/arti... , and https://www.cell.com/current-biology/... . If we ever remake this video, we think it would be neat to discuss these in regard to the host cell.
