Explanation:
Exp:B According to scientist, "Johannes Von Hanstein," tissues of the root is divided into three major parts. (1) vascular cylinder, (2) cortex (3) epidermis. Which is derived from three groups of meristematic cells. Meristematic tissue consists of the cells which have the ability to divide and redivide to form new cells. Dermatogen, periblem, and plerome are meristematic tissues.
- Dermatogen (outermost layer) gives rise to the epidermis.
- Periblem (middle layer) that gives rise to hypodermis, cortex, and endodermis.
- Plerome (innermost layer) that gives rise to vascular tissue including pith.
