WebMay 31, 2024 · Why are there no mitochondria in prokaryotes? Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria. WebSince most eukaryotic cells can't survive without mitochondria (or are at a severe competitive disadvantage without them), this happens for (essentially) all populations of eukaryotes more-or-less 100% of the time ...
