A nail is inserted into a tree's trunk at a young stage of its development. At which height will we find the nail after some years? Will it be found higher or at the same height(What extent of accuracy?) as when it was inserted? I have two specific questions:
Doesn't the intercalary meristem, which is responsible for the increase in internode length, affect the relative position of the nail?
When plants are at a young stage their branches' position would be low but after some years they would have moved higher. How does this happen if growth only happens in the apex? As an example, in the following image the position of the branches changes with time. Why wouldn't the same happen with a nail?
