The model organism for monocots in botany is usually corn (Zea mays). Below, you'll see examples of corn leaf cross sections to demonstrate monocot leaf anatomy.
Monocot leaves have parallel venations as the longitudinal veins run along the length of the leaf that is connected by tiny commissural veins. Dicot leaves have reticulate venation consisting of veins of different sizes connected to form a complex network.
