Draw diagrams of a typical monocot an dicot leaves to show their venation pattern.
Venation is the pattern of distribution of veins and veinlets in the lamina of leaf.It's pattern is different in monocot and dicot leaf.
Reticulate venation is found in dicot leaves while in monocot leaves venation is of parallel type. Biology being a 'Science of exceptions', find out any exception to this generalisation.
