NEET BIOLOGY

Detailed explanation-1: -In dicot stems, the vascular bundles are arranged in a ring. Like dicot roots, dicot stems are protected by an outer layer of dermal tissue called the epidermis.

Detailed explanation-2: -The vascular bundles in the stems of most of dicots are conjoint, collateral and open.

Detailed explanation-3: -The vascular bundles are arranged in circular pattern in dicots and monocot root.

Detailed explanation-4: -In monocot roots, the vascular bundles are arranged in a circular pattern. Monocots and dicots contain two main types of vascular tissue: the xylem and phloem. The xylem carries water and dissolved minerals upward from the roots to the stem and leaves.

Detailed explanation-5: -In the dicot stem, the vascular bundles are arranged in a ring, with pith concentrated at the core of the stem, rather than being scattered throughout the plant interior. In each vascular bundle, the xylem and phloem are separated by a substance called vascular cambium.
