Answer: The formation of veins in the lamina of the surface of the leaves is known as venation. It helps in the conduction of minerals and provides a channel for the translocation of organic nutrients.
Types Of Venation:
Reticulate Venation- network structure is formed by the veins in reticulate venation. Leaves of dicot plants are an example of reticulate venation
Parallel Venation- Veins arise from the mid-rib and run parallel. Parallel venation is found in monocot plants
Furcate Venation- Dichotomous branching is formed by the veins in furcate venation. Leaves of fern are an example of furcate venation
