What is the connection between the different structures ferns use to reproduce?

A. The fertilize egg produces spores.

B. The eggs are fertilized by the spores.

C. The spores grow into new individuals by asexual reproduction.

D. The spores grow into male and female gametophytes that produce eggs and sperm

The answer is D. In the alternation of generation by plants and algae, gametophyte phase is the haploid phase. The gametophyte sprouts from spores that are produced by sporophytes. The gametophyte produces gametes that fuse to form a zygote. The zygote grows into a prothallus that represents the short diploid phase in ferns
