ok so maybe you can explain which parts of the cell can be removed without causing the cell to cease functioning and reproducing.
Even if the answer is no parts can be removed without the cell function ceasing it doesn't matter.
You have fallen for the irreducible complexity trick and you don't understand what is wrong with it.
An irreducible complex thing can be created
not just by adding bits one at a time it can be created by subtracting things too. With that the whole IC argument is dead.
