These are specialized for Photosynthesis and contain Phloem with little or no xylem. Minor Veins branch from the midvein at oblique angles. Consequently, the minor veins may be asymmetrical in cross sections. You may need to scrape of some hairs to see the lower surface. Mount the hairs in water and examine them under the microscope.
Layteral veins get progressively smaller and smaller.
This is called Reticulate or Net Venation . However, close scrutiny shows that they produce Lateral Veins at angles approaching 90 degrees. Thus, they have a type of reticulate venation called Striate . The Important Point to remember is that Monocots and Dicots have vein networks. Note the Variety of Cell Types which have specialized functions.
