In plant anatomy, the 'Vascular cambium' is a lateral meristem responsible for secondary growth (increase in girth) in dicots and gymnosperms. It produces secondary xylem (wood) towards the: MCQ with Answer and Explanation

The vascular cambium is a thin layer of meristematic cells located between the primary xylem and primary phloem in the vascular bundles of dicot stems and roots, and in the secondary vascular tissue. It is a lateral meristem that divides periclinally (parallel to the surface). It produces secondary xylem (wood) cells towards the inside (center) of the stem or root, and secondary phloem (inner bark) cells towards the outside (periphery). Since it produces xylem much faster than phloem, the secondary xylem accumulates and forms the bulk of the wood.
