Greater than 1.5 billion years in the past, a momentous factor occurred: Two small, primitive cells turned one. Maybe greater than any occasion—barring the origin of life itself—this merger radically modified the course of evolution on our planet.
One cell ended up inside the opposite and advanced right into a construction that schoolkids be taught to seek advice from because the “powerhouse of the cell”: the mitochondrion. This new construction offered an incredible energetic benefit to its host—a precondition for the later evolution of advanced, multicellular life.
However that’s solely a part of the story. The mitochondrion will not be the one essential construction inside advanced, eukaryotic cells. There’s the membrane-bound nucleus, safekeeper of the genome. There’s a complete system of inner membranes: the endoplasmic reticulum, the Golgi equipment, lysosomes, peroxisomes and vacuoles—important for making, transporting, and recycling proteins and different cargo in and across the cell.
