In all seriousness, I wish the science world would come up with a new explanation besides "mitochondria is the powerhouse of the cell." Nobody even uses the word "powerhouse" anymore. I don't know wtf a powerhouse is. I've been told mitochondria is the "powerhouse of the cell" for decades, but I don't know wtf that means other than OK it provides power somehow. I guess that's all we need to know about mitochondria.
