​​​​​​​
When a nail is inserted in the trunk of a tree at a height of 1 metre from the ground level. After 3 years the nail will remain at the same position. It doesn’t move upwards as the apical meristem responsible for growth (length) is present in the apices only and lateral meristem responsible of increase in girth will lead to no change in length.
