What are the veins of leaves like?

Veins are like radioactive bouquets The veins on the leaves are as clear as their veins, like human blood vessels and radioactive bouquets. Veins are vascular bundles that grow on leaves. They are branches of vascular bundles in stems. These vascular bundles are distributed to all parts of the leaf through the petiole. The large and obvious vein located in the center of the leaf is called midvein or main vein. Many veinlets that branch from both sides of the midvein for the first time are called lateral veins. A vein that emanates from a lateral vein and is smaller than the lateral vein is called a venule. Veins are staggered, dividing the leaves into countless small pieces. Each small piece has a slender vein tip extending into it, forming a transportation channel in the blade.
