Explain the process of secondary growth | Class 11 Biology Chapter Anatomy of Flowering Plants, Anatomy of Flowering Plants NCERT Solutions

Question: Explain the process of secondary growth in stems of woody angiosperm with help of schematic diagrams. What is the significance?
Answer:

In woody dicots, the strip of cambium present between the primary xylem and phloem is called the interfascicular cambium. The interfascicular cambium is formed from the cells of the medullary rays adjoining the interfascicular cambium. This results in the formation of a continuous cambium ring. The cambium cuts off new cells toward its either sides. The cells present toward the outside differentiate into the secondary phloem, while the cells cut off toward the pith give rise to the secondary xylem. The amount of the secondary xylem produced is more than that of the secondary phloem.

 

Stages of secondary growth in dicot stem

The secondary growth in plants increases the girth of plants, increases the amount of water and nutrients to support the growing number of leaves, and also provides support to plants.
