Detailed explanation-1: -The monocot stem has a sclerenchymatous bundle sheath on the outside of a vascular bundle.

Detailed explanation-2: -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: –Monocots usually have collateral vascular bundles, a type that is also called closed.-The vascular bundle is enclosed by a bundle sheath of parenchyma cells in the cortex region.-Monocot stems have most of their vascular bundles near the outside edge of the stem.-There is no pith region in monocots.

Detailed explanation-4: -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.

Detailed explanation-5: -Monocots have usually collateral vascular bundles, a type that is also called closed. The vascular bundle is enclosed by a bundle sheath of parenchyma cells. Xylem and phloem of the shoots of mono-and dicots are usually arranged opposite to each other in the vascular bundles (collateral vascular bundles).
