Permanent tissues are made up of mature cells which have lost the capacity to divide and have attained a permanent shape, size and function due to division Start studying plant tissues. Is there any sign of secondary phloem differentiation from (a) fascicular or (b) interfascicular cambial regions? 218 terms. 1 A–C; Fig. Most of the derivatives in this interfascicular region will not have differentiated yet, as the secondary vascular tissue forms in this region only after it is well established in the primary bundles. Stem B. Vascular cambium, a type of lateral meristem, is the source of secondary xylem and secondary phloem, but little is known about the molecular mechanisms of its formation and development.
