SUMMARY
The discussion centers on the fate of membrane-bound organelles in eukaryotes that underwent secondary endosymbiosis, specifically those that engulfed prokaryotes. It highlights the uncertainty surrounding the identification of these cells, which are only known through molecular evidence. The conversation references Lynn Margulis's endosymbiotic theory, suggesting that pre-eukaryotes may have possessed internal membranes, although these structures remain unobserved.
