How would plant development change if the functions of the genes SHOOTMERISTEMLESS (STM) and MONOPTEROUS (MP) were reversed?
a. The embryo–suspensor axis would be reversed.
b. The embryo–suspensor axis would be duplicated.
c. The root–shoot axis would be reversed.
d. The root–shoot axis would be duplicated.
How would a loss-of-function mutation in the α-amylase gene affect seed germination?
a. The seed could not imbibe water.
b. The embryo would starve.
c. The seed coat would not rupture.
d. The seed would germinate prematurely.
Which of these is a feature not present in seedless plants that have contributed to the success of seed plants on land?
a. Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from
environmental stresses.
b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought
conditions and UV radiation.
c. Seed germination is solely mediated by water during episodes of heavy rain.
d. Pollen grains, with walls containing sporopollenin, deter herbivores.
