How are the reproductive cycles of a fungus and a pteridophyte similar? a)both organisms form fruiting bodies that produce diploid seeds. b)both organisms produce haploid spores and exhibit diploid and haploid stages. c)both organisms reproduce sexually when two haploid hyphae fuse. d)both organisms exhibit a diploid stage and are only able to reproduce asexually.

The correct answer is option B.

Explanation:

The sporophytes in pteridophytes is the haploid stage and generate spores. The diploid stage in pteridophytes may take place when two spores combine and give rise to a prothallus, that is, the diploid stage of the pteridophytes.  

A fungus to generate spores by the sporangiophores, its haploid stage. However, on certain occasions, two horizontal hyphae between the two species of fungi, may combine at the tips and generate a zygote via plasmogamy and karyogamy.  

d. organisms have cells with different shapes and functions.
