ELI5: if plants age, how can you plant a cutting and still get a normal growth like it was a plant from seed?

Most plants are indeterminate growers, meaning that if they properly care for they can continue to grow for a very long time. A reason a plant might die of "old age" is that they get too big, and therefore have a hard time getting water to their entire system. They're also "perpetually embryonic", meaning that their cells are capable of changing into different kinds of cells, like human stem cells. This is why you can take a cutting and replant it and create a whole new plant.
