If you have a cutting of a Pachanoi, it might come from a plant that is many years old. That plant might also have started as a cutting of a previous plant, and so on.
So, the question is: Do these cacti "remember" how old they are?
Or is a 3-year plant that grew from seed basically exactly the same inside as a cutting that is from an original plant that might be hundreds (thousands?) of years old?
For example, about flowering: If I plant a cutting from one of your old plants, will my new cutting flower more quickly than if I grew a new cactus from seed?
In humans, there's something called a "teleomere", which is a little bit of DNA that gets shorter and shorter every time our cells divide. Like a death clock that will run out.
As far as I know, cacti have no similar mechanism?
Are they immortal? As in being able to continue to grow if they get light, water and don't get sick?
