Wouldn’t grow something from the inside require a very strong force to “move” the already present one? Instead growing from the last “layer” towards the outside would require a lot less force, but perhaps a lot more matter.
Is it even correct that trees grow concentrically?
Now that I think about it, how do plants grow in general? Hahaha
Update: for everyone wondering, yes, my question doesn’t make sense because the i.e. contradicts the question. I don’t want to correct it because I don’t know which part to correct since I was wrong, I thought trees grew new parts inside and pushed older parts outside. So I could correct the i.e. and swap “innemost” with “outermost” but that would mean that people would read a question stating something that is wrong, or I could correct the question and swap “inside” with “outside” but I was wrong and I’m glad I learnt something today. We can all agree that I asked a weird question in a weird way, thank you all for your answers.
Does your skin grow from the outside? Does it even make any sense that it would? Why would trees be different?
OP phrased it weirdly but what they mean is that trees have all growth happen at the surface, not in the middle.
which is actually the opposite of how our skin grows, skin cells grow at the bottom of the skin and are pushed upwards by the new growth and mature as they go, until they reach the surface and die so that they can protect us and easily be shed to make space for new cells.
which is why you’ll see hollow trees being perfectly happy and healthy, whereas a human with an empty space underneath their skin is going to be uncomfortable at best.
Yeah my question was wrongly put but I thought trees did what you described skin does: I thought new tree cells were created in the middle and the outermost layers were the oldest ones.
