A billion and a half years ago, an archaeote from the Lokiarchaeota lineage, ate the aforementioned bacterium (the protomitochondrion), and rather than destroying the bacterium, simply fed off of its amazing capacity to generate ATP. The protomitochondrion became a symbiotic organism within the archaea, and, over time, was incorporated as an organelle - the mitochondrion, the “powerhouse of the cell.” This new method of internal energy generation is what allowed complex life - animals, plants, and fungi, to evolve. Organisms descended from the lokiarchaeote which ate a protomitochondrion are called “Eukaryotes.”

The same thing happened many millions of years later when one of the decedents of a lokiarchaeote ate a different bacterium (called a cyanobacterium), capable of using energy from sunlight to catalyse a chemical reaction which turns carbon, hydrogen, and oxygen atoms from CO2 and H2O molecules into energy storage molecules. Thus, the ancestor to all plants gained the ability to photosynthesise.
