The secondary growth of plants is usually defined as the growth that originates due to the process of cell division in the cambia. This growth allows the stems as well as the roots of the plants to get broad and increases their thickness.
This type of growth is basically essential for the plants that are woody in nature. It is because they have the ability to grow much taller in comparison to the other types of plants, providing the required support for the growth and expansion of stems and roots.
This type of growth produces secondary plant structures that are commonly known as 'anomalous'.
