In which tissue do lateral roots originate
WebLateral roots originate from the pericycle and exhibit a morphology comparable to the primary root. (A) Scanning electron micrograph of an emerging lateral root. Bar, 50 µm. (B)... WebIn eudicots, it also has the capacity to produce lateral roots. Branch roots arise from this primary meristem tissue. In plants undergoing secondary growth, the pericycle contributes to the vascular cambium often diverging into a cork cambium. Cortex, pith and endodermis does not gives rise to lateral roots.
