Question

what is leaf venation?

Answer 1

This is particularly important in the case of the leaf. An understanding of leaf anatomy is impossible unless it is correlated with some knowledge of leaf function

Answer 2

veins pattern parallel leaves. Venation is the pattern of veins in the blade of a leaf. The veins consist of vascular tissues which are important for the transport of food and water. Leaf veins connect the blade to the petiole, and lead from the petiole to the stem.
