Vascular cambium
From Biocrawler, the free encyclopedia.
Vascular cambium is a tissue found in the stems of perennial dicots.
Vascular cambium is a part of the plant's meristem - series of tissues consisting of embryonic (incompletely differentiated) cells from which other (and more differentiated) plant tissues originates. It is a thin (mostly) cylindrical layer between plant's bark and wood (between the xylem and phloem tissues). The vascular cambium grows both inwards and outwards. New cells deposited on the inside make up the secondary xylem; new cells to the outside make up the secondary phloem. (The word secondary differentiates these new tissues from the primary xylem and phloem, which derive from the apical meristem.)
