what is the site of secondary plant growth
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.rising from lateral meristems, secondary growth increases the girth of the plant root or stem, rather than its length.

Secondary Growth in Roots Secondary growth occurs in many roots and usually results in the thickening of the root diameter by the addition ofvascular tissue.Initiation of secondary growth occurs when cells in the residual procambium and parts of the pericyle begin to make periclinal divisions.Only the pericyle cells opposite the xylem points start to make periclinal divisions. The inner layer of cells becomes the vascular cambium.nitiation of secondary growth occurs when cells in the residual procambium and parts of the pericyle begin to make periclinal divisions.
