DENDROLOGY

Detailed explanation-1: -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-2: -Monocot plants contain scattered vascular bundles.

Detailed explanation-3: -Monocot stem vascular bundles are found irregularly scattered in the ground tissue. Towards the periphery, the bundles are smaller in size while towards the centre, they are larger in size. The smaller bundles are younger, while the larger ones are older. Hence, the arrangement is described as centrifugal or endarch.
