2 lut 2023 · The primary function of leaf veins is transporting water, minerals, and food throughout the leaf. The xylem moves fluids from the root upwards, entering the leaf through the midrib and then branching off with the help of venules.
Leaf veins are vascular bundles coming to the leaf from stem. The arrangement of veins in a leaf is called the venation pattern. Frequently, there is one or more main vein (primary vein) and secondary veins that branch from it. Tertiary veins branch from secondary veins (F igure \(\PageIndex{11}\)). Figure \(\PageIndex{11}\): The main (primary ...

Expanding Your Knowledge: Collect specimens from trees and shrubs in your area. For each, determine the type of leaf and the arrangement of the leaves on the stem.
Inside plant veins are two different types of tissues. Xylem carries water and minerals up from the roots of the plant and phloem carries the sugars (nutrients) away from the leaf to areas where the plant is growing or to storage areas in the plant. 9.
