These structures can be classified as actinodromous, acrodromous, campylodromous, parallelodromous, or (*) pinnate, depending on the patterns of their veins.
Near the end of his career, W.D. Hamilton proposed a coevolutionary explanation for a striking physical feature of these structures. Six carbon aldehydes, alcohols, and esters make up the "volatiles" named for these structures that are released during tissue damage. The genus Fenestraria is so-named because it possesses a modified type of these structures resembling a translucent window. Christen C. Raunkiaer devised a scheme to classify the size of these structures by increasing orders of nine. These structures can be classified as actinodromous, acrodromous, campylodromous, parallelodromous, or (*) pinnate, depending on the patterns of their veins. Vertically-oriented palisade cells within these structures are responsible for most of their biochemical activity, and sit above their mesophyll layer. The cotyledon acts as one of these structures inside a seed. Fern fronds are analogous to these structures. For 10 points, name these chlorophyll-abundant plant structures that branch off of stems.
