Transport in plants

Does anyone know why absorption occurs behind the tip of a root and not on the actual tip? Any help would be greatly appreciated :smile:

This is because the root hairs erupt from these cells of the roots.
As you well know (or I believe you should but I don't know the stage your at), the very tips of the roots are meant for mitosis and as a result, are aimed at growing hence why when you get a plant's roots you are told to cut them from the tip to monitor mitosis occurring. =)

And as you know, the root hairs are used for absorption of nutrients dissolved in water as well as water itself.
