Which statement accurately describes the difference between the fascicular and interfascicular cambium?
Fascicular cambium produces secondary xylem, while interfascicular cambium produces secondary phloem.
Fascicular cambium is present in monocots, while interfascicular cambium is present in dicots.
Fascicular cambium arises within vascular bundles, while interfascicular cambium arises in the medullary rays.
Fascicular cambium is a primary meristem, while interfascicular cambium is a secondary meristem.
