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 ...

31 paź 2023 · The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation. The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.
18 kwi 2013 · The design and function of leaf venation are important to plant performance, with key implications for the distribution and productivity of ecosystems, and applications in paleobiology, agriculture and technology. We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation.
The arrangement of veins in a leaf is called the venation pattern. Monocots and dicots differ in their patterns of venation ( Figure 30.22 ). Monocots have parallel venation; the veins run in straight lines across the length of the leaf without converging at a point.
Identify the parts of the angiosperm leaf. Describe some of the ways in which leaf parts differ from plant to plant. Recognize the basic patterns of leaf shape and orientation of the veins in the leaves. Leaves are shoot structures that attach to stems and branches at nodes.
We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance.
