Imagine That Angiosperms Were Suddenly Unable to Control Their Time

Imagine that angiosperms were suddenly unable to control their time of flowering. What would be the result?

A) Because angiosperms have long life cycles, there would be little effect; if plants failed to reproduce one year, they will likely compensate by producing more flowers the following year.
B) There would likely be little effect because angiosperm pollinators are present year round (i.e., insects in the spring/summer and birds in the fall/winter) .
C) There would likely be little effect because angiosperm pollen is able to survive on plant surfaces for months at a time.
D) None of the answer options is correct.
