Question

. A nail inserted some years back at 1.5 mtr height on a tree trunk shall (A) remain where it was (B) move upwards (C) move downwards (D) move laterally​

Answer:

A) Remain where it was

As primary meristem is responsible for apical growth and secondary meristem only for girth and the nail is inserted in secondary meristem not in primary apical meristem. So, the nail will be at same position.
