Detailed explanation-3: -The special arrangement of veins in a leaf is called as venation.
Detailed explanation-4: -A leaf is often organized with one main vein running down the middle of the blade. This vein is called the midrib. All of the veins, the petiole, and the midrib help position the blade so that it is facing the light source. Veins of flowering plants are found in several patterns.
Detailed explanation-5: -Three major venation patterns in simple leaves are “palmate”, “pinnate”, or “parallel” (Figure 17, left to right). Typically there is a prominent central vein (the midrib) running from the leaf base to its tip.
