Apparently, after cells die, they can sometimes come back to life -- even if their DNA and organelles have been ripped apart. They apparently have natural repair mechanisms that can fix all that: https://www.quantamagazine.org/cell-death-anastasis-and-resurrection-20190708/

    It kind of makes sense: one theory about the emergence of cells says that proto-cells reproduced "statistically" and function "statistically". (Freeman Dyson calls this the "garbage bag theory" of the emergence of life.) These proto-cells are just a bag of chemicals that play off each other. Over time, the functioning becomes more streamlined and modular, leading to well-defined organelles and long chains of DNA and RNA.

    When cells "die", the statistical structure remains intact; only the rigid modular structure gets broken apart. Returning to the realm of the living amounts to retracing steps through evolutionary history, from a form a little more organized than Dyson's "garbage bags", to perfectly-formed, present-day living cells.
