Regions of root from the root tip to base are
a)	Region of maturation  Region of elongation  Region of meristematic activity
b)	Region of elongation  Region of maturation  Region of meristematic activity
c)	Region of meristematic  Region of elongation  Region of maturation
d)	Region of dividing  Region of maturation  Region of elongation

(c)

A typical root possess the four parts or regions

(i) Root Cap The root is covered at the apex by thimble like structure called root cap. It protects the tender apex of root as it makes its way through soil

(ii) Region of Meristematic Activity Few millimeters above the root cap. The cells of this region are very small, thin walled and dense protoplasm. They divide repeatedly

(iii) Region of Elongation The cells proximal to the meristematic zone undergoes the rapid elongation and enlargement and are responsible for growth of root in length

(iv) Region of Maturation The cells of elongation zone gradually differentiate and mature. This zone lies just proximal to the region of elongation
