DENDROLOGY

Detailed explanation-1: -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-2: -In general terms, therefore, leaf venation patterns in monocots tend to be parallel and closed whereas those in eudicots are reticulate and can be either open or closed.

Detailed explanation-3: -Parallel veins are found on monocots, while dicots have veins that form a branching pattern. Consider the “leaves” of grasses.

Detailed explanation-4: -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.
