Detailed explanation-1: -The vascular cambium arises between the primary xylem and phloem of a young stem or root. Parenchymatous cells become meristematic and begin to produce secondary xylem or wood toward the inside of the cambium and secondary phloem toward the outside of the cambium.
Detailed explanation-2: -Secondary xylem and secondary phloem are produced from a cylinder of meristematic tissue within the woody stems and roots. This cylinder of meristematic tissue is the vascular cambium. The secondary xylem provides additional structural support and additional water conduction tissue in shrubs and trees.
Detailed explanation-3: -Complete answer: The reason for the phenomenon that Vascular cambium forms xylem on the inner side and phloem on the outer side is the differential action of hormones.
Detailed explanation-4: -The vascular cambium produces secondary xylem on the inside of the ring, and secondary phloem on the outside, pushing the primary xylem and phloem apart. The vascular cambium usually consists of two types of cells: Fusiform initials (tall, axially oriented) Ray initials (smaller and round to angular in shape)
