Endosymbiotic theory
Storyboard Text
- Ugh! I'm going to flunk my quiz over the Endosymbiotic theory!
- Dude, it's so easy. I'll explain.
- Okay, I get it so far. I think.
- Well, the theory basically says that eukaryotic cells and organelles such as mitochondria came from the folds of the membrane of a prokaryote.
- So, to start. Organelles in cells didn't just come out of thin air. This was noticed and someone came up with a theory. Come on, I'll show you evidence.
- Okay, right behind you!
- Follow me, we'll use this empty science room.
- Ok so lets say these little things are prokaryotes. We know that these are the types of organisms or cells that have NO nucleus. Keep in mind that it has a cell membrane.
- Right. All cells have a cell membrane which is semipermeable! It is made up of a lipid bilayer.
- Right. Now, organelles. They had to come from somewhere! The same goes for eukaryotes. This is where the endosymbiotic theory comes in.
- Oh! That makes total sense. I was just over thinking it. I think I'm ready for my quiz, thanks!
- Mitochondria
- Mooooom! I made an A on my quiz...thanks to Avery for the crash course;)
