procambium

pro·cam·bi·um

P0575700 (prō-kăm′bē-əm)n. The primary meristem that gives rise to vascular tissue.

pro·cam′bi·al (-əl) adj.

procambium

(prəʊˈkæmbɪəm) n, pl -bia (-bɪə) (Botany) undifferentiated plant tissue, just behind the growing tip in stems and roots, that develops into conducting tissues[C19: from pro-² + cambium] proˈcambial adj

pro•cam•bi•um

(proʊˈkæm bi əm)

n. the meristem from which vascular bundles are developed. [1870–75; < New Latin] pro•cam′bi•al, adj.

Procambium

procambium

[prō′käm·bē·əm] (botany) The part of the apical meristematic tissue from which primary vascular tissues are derived.

Procambium

the lateral meristem of a plant from which are differentiated the primary vascular tissues and bundles. The procambium arises in the form of meristematic strands in the growing point of a shoot when leaf traces appear, or it develops in the form of a solid cylinder (or ring) in the growing point of the root in the middle of the primary meristem. The procambium is characterized by intensive longitudinal cell growth and by the elongated (prosenchymal) shape of the cells. Cell division occurs in various directions, with vascular tissues— primary xylem and phloem—arising from the cells. After the formation of vascular tissues in the bundles of gymnospermous and dicotyledonous plants, the procambium functions as cambium. In monocotyledonous plants, the procambium is exhausted completely during the differentiation of closed vascular bundles in the tissue.
