Because a larger predator cell swallowed you and to avoid death you decided to give it all of your excess energy in exchange for protection and this relationship of the weak sacrificing their most valuable assets in order to survive eventually became embedded in the genetic code of all organisms in your ecosystem? Because if so, gimme your cigarettes, gimme your rations, and I’ll be taking the top bunk.
I think that’s actually why cells have mitochondria. Big predator cell ate small prey cell that figured out it wouldn’t get digested if it threw off a bunch of energy which allowed predator cell to be stronger and more advanced. The symbiotic relationship ‘magically’ became how cells evolved to have mitochondria. I know this because I’m Bill Nye. Can confirm.
Mitochondria are basic cells that were absorbed and formed a symbiotic relationship. Predatory is a stretch, but the gist is there. Even symbiotic would be pushing it though, because if you really think about it, any cell without them that needs them would die. The mitochondria might (not likely) survive. Who's who's bitch now!? Bwah lol
In other words, any mitochondria that leaves its host cell becomes the Aaron Hernandez of the cellular world. That’s right, mitochondria. Get back over here and put on this blonde wig so I can tell you how purdy you look tonight. And don’t forget those cigarettes and rations I told you about a few minutes ago.
I'll just go full-nerd for a second here, feel free to skip:
-Prokaryotes have no organelles and basically function as their own mitochondria.
-Mitochondria are most likely descended from an ancient version of modern cyanobacteria.
-If mitochondria packed up and left eukaryotic cells, prokaryotes would most definitely inherit the earth. Eukaryotes typically have dozens or hundreds of mitochondria.
-Mitochondria gave up all but twelve genes from their original genome to their host's nuclear dna, so they are totally dependant now.
-In prison, you fight for the bottom bunk not the top bunk :p
