Big Bend National Park in Texas is mostly Chihuahuan desert where rainfall averages about 10 inches per year.Yet when hiking in this bone-dry desert,it is not uncommon to encounter mosses and ferns.One such plant is called "flower of stone." It is not a flowering plant,nor does it produce seeds.Under arid conditions,its leaflike structures curl up.However,when it rains,it unfurls its leaves,which form a bright green rosette on the desert floor.Consequently,it is sometimes called the "resurrection plant."
-Upon closer inspection of the leaves of flower of stone,one can observe tiny,cone-like structures.Each cone-like structure emits spores of two different sizes.Further investigation also reveals that the roots of flower of stone branch only at the growing tip of the root,forming a Y-shaped structure.Consequently,flower of stone should be expected to possess which other characteristics?
1) a gametophyte generation that is dominant
2) lignified vascular tissues
3) microphylls
4) spores that are diploid when mature
