Before revision: The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding.Buchanan, Gruissem, Jones, Biochemistry & molecular biology of plants, 1st edition, American Society of Plant Physiology, 2000
After revision: It is most prevalent in the Ground tissue found in vascular plants, with Collenchyma having little to no lignin, and Sclerenchyma having lignified secondary cells walls.The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding.Buchanan, Gruissem, Jones, Biochemistry & molecular biology of plants, 1st edition, American Society of Plant Physiology, 2000
