The upcoming discussion will update you about the differences between Secondary Growth of Dicot Steam and Dicot Roots.
Difference # Secondary Growth of Dicot Steam:
1. The vascular cambium is in the form of a circular strip or ring from the beginning.
2. The vascular cambium is made up of both primary (intra-fascicular) and secondary (inter-fascicular) strips of meristematic tissues.
3. The vascular rays are narrow from the beginning.
4. Ray initials are not grouped in a particular region.
5. Annual rings are quite common.
6. Phellogen arises from a superficial layer of the cortex.
Difference # Secondary Growth of Dicot Roots:
1. The vascular cambium is a wavy band in the early stages of its activity.
2. The vascular cambium is secondary in origin. It is formed of conjunctive parenchyma and pericycle.
3. Initially the vascular rays are wide and arise opposite the protoxylem points.
4. Ray initials arise from the pericycle part of vascular cambium.
5. Annual rings are absent.
6. Phellogen generally originates from the pericycle.
