Pericycle of dicot root form lateral roots
WebAug 10, 2012 · Inner to endodermis there is pericycle. Lateral roots begin from the pericycle. Vascular tissues, phloem, and xylem are arranged alternatively as a ring. Dicot Root. Dicot roots have two growth phases as primary growth phase and secondary growth phase. When a seed grows, the radical becomes the tap root combined with lateral roots. WebLateral roots are produced when cells in the pericycle, the layer of cells surrounding the central vascular cylinder, begin to divide, form additional cell layers that push through the outer cell layers of the primary root, and ultimately organize a second root meristem. Many lines of evidence indicate that lateral root development is promoted ...
