The cell wall is the wall of the cell.

of the cell

Human cells also don't have chloroplasts. Maybe the cell membrane is the fence of the cell.

To add to that, similarly like there are microscopic and macroscopic processes we can only indirectly perveive, there are probably also processes on a much smaller and much larger timescale we can therefore only indirectly perceive.

Like one cell could be the whole universe of some absurdly small conscious beings with a lifespan of less than a femtosecond.

the mitochondria is the cell of the cell

Cells within cells within cells, interlinked

For real? Any tips for those of us having problems?

Phew. Ok. Ive got that one down.
Depending on the day.

As a German, I’ve definitely learned that in school. Maybe it was memes by then as well, but it being the late 90s I doubt it.

i don't even remember learning about the mitochondrion in school lmao

I think "endoplasmatisches Retikulum" is a more memorable phrase we learn or meme about

Bodo Wartke - endoplasmatisches Retikulum

All of us who learned Spanish in the U.S. also know "¿Dónde está la biblioteca?"

Just a bunch of canned phrases like that kicking around in our brains.

As a Canadian, I share your confusion. I think that phrase was just a common descriptor of mitochondria in US textbooks, or a catchy line in a popular US biology video.

It's just strange enough to make a big impression on bored students, so I'm not surprised it's been memed so hard.

[Playful] Don't force it there.

unironically it's pretty strange that i've never even heard of people trying to rectify this, surely someone has tried plonking some choloplasts in a skin cell culture and seeing how it goes?
