each vein contains xylem to bring water and minerals containing sap into the leaf and each leaf has phloem that carries sap of manufactured food ut of the leaf.
The purpose of the veins of a leaf is to hold nutrient and carry out the role of photosynthesis.
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 Veins in the leaf
The network of veins is the leaf skeleton
in veins
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.
There are two tissues within those veins, xylem and phloem. Xylem carries water from the roots up to the cells in the leaf. Phloem carries the food produced in the leaf to the rest of the plant. Bottom line is the leaf has veins for the same reason we have arteries and veins, to move stuff around to where we need it.
the veins are parallel to each other
A leaf is a cell that has both chlorophyll and veins.
