Plants have an intermediate body form called a sporophyte that undergoes meiosis. The cells produced grow, through mitosis, into another intermediate body form called a gametophyte, which divides by mitosis to form gametes. The gametes fertilize, and the zygote grows, through mitosis, into another sporophyte. This form of a sexual life cycle is referred to as

A. alternation of generations.
B. crossing-over.
C. polyploidy.
D. an asexual life cycle.
E. germination.
