List and describe examples of modified leaves. Mckown, kristen frole, michael rawls, j. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance. Web we synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. Some leaves are attached to the plant stem by.

Identify a Tree by Leaf Shape, Margin, and Venation

The numbers of secondary veins are independent of the length of the main vein, and the total length of veins increases linearly with the leaf perimeter. And (3) modification of both the vein pattern and source distribution by leaf growth. We developed a mathematical model that is based on the positive feedback regulation between plant hormone auxin and its efflux.
