Answer 2

Answer:

The arrangement of veins and veinlets in the lamina of the leaf is known as venation. It is of two types:-

Reticulate venation, the lateral veins divide and re-divide to form many veinlets. These are arranged in a net-like fashion or reticulum. It is the characteristic feature of dicot plants.

Parallel venation, veins, and veinlets run parallel to each other and are the characteristic feature of monocot plants.
