As the cells of the root cap are destroyed and sloughed off, new parenchyma cells are added by a special internal layer of meristematic cells called the calyptrogen. [1] It is also called calyptra. The zone of cell division is closest to the root tip; it is made up of the actively-dividing cells of the root meristem. These roots are very tasty because they have stored much of the sugar and nutrients the plant needs to survive. As cells are lost among the soil particles, new ones are added from the meristem behind the cap. 1.
