The formation of secondary vascular tissues from the cambium is a characteristic feature of dicotyledons and gymnosperms. In certain monocots, the vascular tissues are also increased after the primary growth is completed but the cambium of these plants is of a different nature. See more In botany, secondary growth is 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 … See more Abnormal secondary growth does not follow the pattern of a single vascular cambium producing xylem to the inside and phloem to … See more In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium.
