Answer:

The arrangement of veins and veinlets on the lamina of a leaf is called venation. There are two types of venation, reticulate and parallel venation.

Reticulate venation: in some leaves, the veins and veinlets are irregularly distributed over the entire lamina, forming a network. Such leaves are said to have reticulate venation. For eg., grass, wheat.

Parallel venation: in some leaves, the veins and veinlets run parallel to each other. Such leaves are said to have parallel venation. For eg., rose, mango.
