WebThe three structures, phellem (cork), phellogen (cork cambium) and phelloderm constitute the periderm, a protective tissue that replaces epidermis in stems and roots, which increase in diameter when secondary growth occurs. Cork cambium produces more cork layers than phelloderm layers. WebDec 21, 2010 · The first cork cambium typically arises in sub epidermal cells or cells of the cortex in stems while the subsequent cork cambia originate in the secondary phloem. The …

But when phellem starts … Web(A) Primary xylem and phloem differentiate from procambial tissue in the vascular bundles, and a fascicular cambium is formed from procambial tissue separating these tissues. (B) Later, an interfascicular cambium appears between the vascular bundles that is continuous with the fascicular cambium.
