Question 15

Please use the following information to answer the questions below.
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."
-In which combination of locations would one who is searching for the gametophytes of flower of stone have the best chance of finding them?
