NEET BIOLOGY

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: -The cambium which is located within the vascular bundles, that is between the primary phloem and primary xylem is called the intrafascicular cambium.

Detailed explanation-3: -The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain other vascular plants.

Detailed explanation-4: -Solution : In gymnosperms and dicot stems a strip of vascular cambium occurs between phloem and xylem of each vascular bundle. It is called intrafascicular (or fascicular) cambium. This strip of vascular cambium later produces secodary tissues. Such vascular bundles are described as open.

Detailed explanation-5: -In dicot root, parenchyma tissue is found between the xylem and phloem. This tissue is called as conjunctive tissue.
