This is an interesting question: "How much membrane is in a cell?".
In this video, I use a football and some sheets of material to explore how much membrane we have in a cell and which organelles have the most membrane.
This was a fun video to make, and I got some very odd looks from passing dog walkers.
If you would like to say thanks for the fact sheet, then please feel free to buy me a coffee at https://www.buymeacoffee.com/drnickm
