In the Great Australian Desert, Rainfall Averages About 30 Centimetres

question 79

Multiple Choice

In the Great Australian Desert, rainfall averages about 30 centimetres per year. Yet, it is not uncommon when hiking in this extremely arid zone 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". At first glance, it could be a fern, a true moss, or a spike moss.
-In which combination of locations would one who is searching for the gametophytes of "flower of stone" have the best chance of finding them?

• A) in moist soil
• B) in moist soil and underground, nourished there by symbiotic fungi
• C) in shady, moist places and underground, nourished there by symbiotic fungi
• D) in shady, moist places, far from any "flower of stone" sporophytes
