Branching veins mean that they expand over the area of a leaf. All leaves tend to have branching veins, with few exceptions.
The veins on the leaves of dicot plants branch out pinnately or palmately. Pinnate has a central vein called midrib where the small veins are attached.
Venation is how a the leaf veins are organized. Netted venation is when there are larger veins with many smaller veins branches making a type of web pattern.
The patten of veins on a dicot leaf are called netted veins. With netted veins, several main veins begin near the base of the leaf and radiate outward.
The stem. Leaves do branch off the stem; however, it is the veins of the leaf that give the leaves their support. Just like the stem, the veins are composed of xylem and phloem (vascular tissue).
The network of veins is the leaf skeleton
leaf vessels
The Veins in the leaf
in veins
The spaces between leaf veins are called areoles or areolae.
The fine network of lines on the undersurface of a leaf are called Veins. The water and minerals go to every part of the leaf through these Veins.
Monocot leaves, like those in corn, have parallel veins that don't branch out. Dicot leaves, on the other hand, are netted, branching out in a webby pattern.
