Detailed explanation-1: -The vascular bundles in the stem are arranged around a ring of cambium, which contains cells that divide to expand the girth of the stem.

Detailed explanation-2: -All leave develop from that growing point rather than along the plant stem. Dicots have veins that form a branching network arrangement. The growing point for leaves is a bud on a stem.

Detailed explanation-3: -Dicot stems have a well-defined epidermis with cuticle, a layer of dermis along with multicellular stem hair. The internal structure of a dicot stem mainly consists of epidermis, hypodermis, cortex endodermis, pericycle, vascular strand and pith. Sunflower and Cucurbita are examples of dicot stems.

Detailed explanation-4: -Dicot leaf A leaf with a pinnated pattern (like a feather) has a central vein running down the middle of the leaf with other veins branching off to either side of it. A leaf with a palmate pattern has veins branching out from a single one to form a shape resembling the palm of a hand.

Detailed explanation-5: -Monocot stems emerge from the plumule of the undeveloped organism and frequently have a terminal bud at the tip of the shoot. The stem is decidedly phototropic, in contrast to the roots. The stem emits leaves and branches at structures called hubs that are available at standard spans on the stem.
