Have you ever wondered how some plants can withstand heavy winds? At lease one group, the cattails, produce specialized support structures within their cells to cope with winds. This is great, especially when growing near a large, windy water source.
A team of researchers recently took a much closer look at the leaf cells of a variety of cattail species (genus Typha). For decades, there has been knowledge of fibers that traverse the air chambers within the cells. These have largely been ignored but as it turns out, they indeed serve a purpose.
As any good engineer will tell you, if a structure is to remain sound, it needs multiple avenues in which stress can be redistributed. The same goes for living structures like leaves. The fibers are arranged within the cells makes them quite strong under tension. In this way, multiple load paths are created to distribute the stress of high winds on the leaves. We like to take credit for most of our ideas but, time and again, nature beat us to it first.
