Vedclass · Answer

(C) According to the histogen theory proposed by Hanstein,the root apex is composed of three distinct layers of meristematic tissue called histogens.These three histogens are:$1$. Dermatogen: The outermost layer that gives rise to the epidermis (epiblema).$2$. Periblem: The middle layer that develops into the cortex.$3$. Pleurome: The central core that gives rise to the stele (vascular cylinder).Therefore,there are $3$ histogens present at the apex of the root.
