The diploid generation of the plant life cycle always the diploid generation of the plant life cycle always produces spores develops from a spore is larger and more conspicuous than the haploid stage produces eggs and sperm is called the gametophyte

The diploid generation of the plant cycle always  produces spores. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation  between these diploid and haploid stages that occurs in plants is called the alternation of generations. 

Since a female is both xx chromosome and the male passes down the x chromosome, than the offspring would be female since a female is xx.
