Is the site of origin for lateral roots

(B) The pericycle in roots is composed of thin-walled parenchymatous cells. It is never sclerenchymatous because it is the site of origin for lateral roots. Lateral roots are endogenous in origin,meaning they arise from the pericycle cells. If the pericycle were sclerenchymatous,the lateral roots would not be able to emerge through the cortex and epidermis.
