OBJECTIVE FORESTRY

Detailed explanation-1: -The vascular bundles of monocotylenous plants do not contain a layer of meristematic tissue (cambium) as the dicots do. Thus, no new cells can be formed inside the vascular bundles of monocots and their vascular bundles are termed as closed, whereas those of dicot plants are open.

Detailed explanation-2: -The monocot stem is composed of an epidermis, xylem and phloem (vascular bundles). The vascular bundles in a monocot stem are scattered throughout the origin of the stem underneath the epidermis. The scattered arrangement of the vascular bundles is a key characteristic that separates herbaceous dicots from monocots.

Detailed explanation-3: -In monocots stem, the vascular bundles are scattered across the stem without any definite arrangement. On the other hand, in dicots stem, the vascular bundles are arranged in the form of one or two broken circular rings, following that they have a definite shape.

Detailed explanation-4: -In the dicot stem, these vascular bundles are well arranged in a circular manner and on the other hand in the monocot stem these vascular bundles are scattered throughout the cross-section of the stem.
