The organelle is the fourth example in history of primary endosymbiosis—the process by which a prokaryotic cell is engulfed by a eukaryotic cell and evolves beyond #symbiosis into an organelle. #nature #water #nitrogenfixation https://phys.org/news/2024-04-scientists-nitrogen-organelle-1.html
Scientists discover first nitrogen-fixing organelle
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.
