A root lengthens primarily because of???

Question

a. cell division at the apical meristem.

b. cell elongation.

c. root cell specialization

d. cell division at the root cap.

Answer 1

A) cell division at the apical meristem.

Then the cells elongate (Zone of elongation - behind the meristem).

Then the cells specialize.

Root cap is a protective covering over the apical meistem and does not give rise to root lengthening.
