No worries I am not sensitive to some technical discussion and although I have spend most my life on plants and plant science related fields I am not an expert and continue learning. And yes I got a bit carried away from “dumbing” down but I do think it is important to understand (over time) concepts like phototropism, gravitropism, apical dominance and sink source relationships in plants as it will help you to understand why a tree does what it does. These mechanisms have a big effect on the response of trees and plants but they are often also highly interdependent.
