The reconstruction of Asteroxylon in Figure 21-10 shows thin, leaf-like flaps of tissue on the plant’s surface. What are these called? Did they ever have stomata in any of the zosterophyllophytes? Did they have vascular bundles? Did they ever become large (Hint: Look at Figure 21-13)?
Pines and other plants that grow in very cold climates have sunken stomata just like the plants of the desert, yet the annual precipitation where they grow may be very abundant.  Is there any advantage to their having such a modification?
Early botanists admired ferns but found their life cycle perplexing. In the 1700s, they learned to propagate ferns by sowing what appeared to be tiny dust like “seeds” that they collected from the undersides of fronds. Despite many attempts, the botanists could not locate the pollen source, which they assumed must stimulate these “seeds” to develop. Imagine you could write to these botanists. Compose a note that explains the fern life cycle and clears up their confusion.
