The apex in this case will describe a circle, or rather a spiral, as it is elongating all the time, pointing to all points of the compass in succession.
If a growing stem receives stronger illumination on one side than another, its apex slowly turns from the vertical in the direction of the light source, continuing its change of position until it is in a direct line with the incident rays.
Even the root tip, which shows a certain differentiation into root cap and root apex, cannot be said to be a definite sense organ in the same way as the sense organs of an animal.
