Detailed explanation-1: -Leaf veins–In monocots, there are usually a number of major leaf veins which run parallel the length of the leaf; in dicots, there are usually numerous auxillary veins which reticulate between the major ones.

Detailed explanation-2: -The vascular structures of monocot leaves form parallel veins. Monocot leaves differ from dicot leaves in several ways. First, they tend to be more oblong or linear in shape, and their vascular bundles are organized into veins that originate at the base of the leaf and run parallel to one another.

Detailed explanation-3: -In monocots, the primary venation runs longitudinally for nearly the length of the leaf. Monocot veins undergo divergence at the base of the lamina and converge and fuse toward the leaf apex. Their venation pattern is termed striate. The venation of grass leaves is used as an example of vascular patterning in monocots.

Detailed explanation-4: -Monocots have “Parallel” or Striate venation which is characterized by veins which run parallel to one another over a large expanse of the Blade (Lamina).
