In plant science, secondary growth refers to the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth. If they do have secondary growth, it differs from the typical pattern of other seed plants.
In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the girth of the plant root or stem, rather than its length. As long as the lateral meristems continue to produce new cells, the stem or root will continue to grow in diameter. In woody plants, this process produces wood, and shapes the plant into a tree with a thickened trunk.

Secondary Growth in Plant Stem. Secondary growth in stelar region causes increase wood, cambial in girth of plant. Vascular cambium due to its meristematic activity divides cells into secondary xylem and secondary phloem. Secondary xylem is produced largely than secondary phloem. Secondary xylem is called wood. Due to different cambial activity in a year two growth rings are formed, these rings can determine the age of a plant. Growth rings are also called annual rings. Wood can be classified into heart wood and sap wood. Porous and non porous wood. Manoxylic and pycnoxylic. Xylotomy. Biology videos. Biology lectures. Snober's biology. Botany videos. Botany lectures. Anatomy of plant. Wood anatomy.

In this lesson we revise the structure of the dicotyledonous stem, we discuss primary grown & secondary thickening, we look at annual rings as well as consider the difference between autumn wood and spring wood. Finally, we take a quick look at related terminology.
