Steve, I hope one of the real biologists on the list will give you
a more precise answer.  As far as I know, root hairs are extensions
from individual cells.  I'll just make a wild guess that a root cell
is on the order of 1-10 microns in diameter and a root hair is 0.1 to
1 micron in diameter, and about the length of the diameter of the body
of the cell.

I hope this helps, or at least helps flush someone with Real Facts
out of the underbrush.
