Detailed explanation-1: -In monocot stems, the vascular bundles are scattered throughout the ground tissue. Like monocot roots, monocot stems are protected by an outer layer of dermal tissue called the epidermis. The rest of the stem is made up of ground tissue and vascular tissue.
Detailed explanation-2: -In the monocot stem, the vascular bundles are arranged into xylem and phloem cells which are present in a scattered form throughout the ground tissue. Ground tissue is differentiated into stelar and extra stelar. Ground tissue is not differentiated. Vascular bundles are less in number.
Detailed explanation-3: -The vascular bundle encloses both xylem and phloem. The xylem is present in the inner surface and phloem in the outer surface and cambium is not present in monocot plants. Hence, the vascular bundles in monocot stem are endarch, closed, and collateral. Thus, the correct answer is ‘D’.
