Detailed explanation-1: -All the veins originate at the base of the leaf and are parallel to each other in each lobe of the leaf, while dicots form “branching veins” also called reticulate venation. Their veins branch out on either side of the leaf from the middle vein, forming a web-like structure.

Detailed explanation-2: -Monocot leaves tend to have parallel venation, as opposed to the branching patterns seen in eudicots. Figure 13.2.

Detailed explanation-3: -Monocotyledons have one cotyledon in the embryo. Leaf veins are reticulated (branched).

Detailed explanation-4: -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-5: -Dicot plants have dorsiventral leaves, which have a clear dorsal or upper surface with thicker cuticle and few or no stomata, compared to the lower surface. Monocot plants, on the other hand, have isobilateral leaves, with stomata on both surfaces, and equal thickness of cuticle on both surfaces as well.
