Detailed explanation-1: -One characteristic of that classification, that holds true in modern taxonomy, is the shape of the leaf. Monocot leaves are typically narrow and elongated with parallel veins, while dicot leaves are usually more round-shaped with reticulate veins [1].

Detailed explanation-2: -Dicot leaves are not as linear in shape as monocot leaves, and their vascular structures form net-like veins, instead of parallel ones.

Detailed explanation-3: -Grasses-Grass seedlings have only one seed-leaf (monocotyledons). Their leaves are generally long and narrow with parallel veins. Leaves arise alternately from the nodes, have two parts: a lower portion called the sheath, and an upper portion called the blade.

Detailed explanation-4: -Examples of plants with parallel veins are sedges, cattails, lilies, irises, and grasses (e.g., corn, rice, wheat, turf grasses).
