The main function of the veins is to protect the leaf and give support to its shape and structure through its extended network. The next main function is to supply water and mineral salts from the xylem and the phloem respectively to the parts of the leaf from the stem.
The veins are small tube like structures that pass through a leaf. The leaf has 2 types of venation the parallel venation and reticulate venation.
