They contain xylem and phloem. Xylem moves water up and phloem moves glucose up or down.
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 are parallel to each other
To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day. The leaf was more green in the veins and more discolored farther away from the veins. This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?
The Veins
The main function of the leaf vein is to transport water, minerals, and sugars throughout the leaf. Veins also provide structural support for the leaf and help in distributing nutrients evenly. Additionally, leaf veins play a role in the exchange of gases, allowing for the entry of carbon dioxide and the release of oxygen during photosynthesis.

Leaves are made up of a stem (petiole), a leaf blade (lamina) and stipules which attach at the base of the stem. Leaves contain an epidermis that covers the surface of the leaf, a mesophyll (located inside the leaf that is the primary location for photosynthesis in the plant), and an assortment of veins that run through the mesophyll. The veins are made up of xylems (tubes that bring water and minerals from the roots of a plant to the leaf) and phloems (tubes that move sap produced by phtosynthesis out of the leaf)
The Veins in the leaf
leaf vessels
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.
The spaces between leaf veins are called areoles or areolae.
A leaf is a cell that has both chlorophyll and veins.
the veins are parallel to each other
The placement of the veins in a leaf can limit the effects of photosynthesis and transport water through the leaf and plant body. The location of the veins and the shape of the leaf are two of the factors used to determine the species of the plant.
