Final answer:
The statements about seed dormancy and plants absorbing moisture from the air are true. Seeds can stay dormant in the soil until conditions are favorable for germination such as rainfall, and some plants are adapted to take moisture from the air.
Step-by-step explanation:
The statement that 'seeds lie in the ground until rain falls' is true. Seeds have adapted to remain dormant in harsh conditions, waiting for the appropriate environmental signals, such as rain, to begin germination. Dormancy is a survival mechanism that allows seeds to withstand drought and other adverse conditions for months, years, or even decades. This biological adaptation allows plants to disperse their progeny through time, an ability unique to seed plants.
As for the second part of the statement, 'some plants take moisture from the air through their leaves', it is also true. Plants, such as epiphytes that live in moist environments, can absorb water directly from the air through specialized structures. Others may have highly adapted leaves with sunken stomata to reduce water loss and effectively collect water from the atmosphere.
