Abstract
In Guttenberg’s review5 of root caps, their functions are listed as protecting the meristem from damage and acting as a drilling tissue through the earth. Both of these functions are served by the outer two or three layers of cells forming the cap periphery; a third function, the perception of gravity (Juniper and French12) is provided by the cells of the cap columella or core cells (Fig. 1)
