Answer:
Mitosis, mitosis
Step-by-step explanation:
Both ferns and mosses produce gamete by mitosis.They reproduce by releasing large number of spores that are free to move by any carrying agent such as air.
Ferns are able to produce both sexually and asexually. However, when it reproduce asexually it produces haploid spore that further convert into haploid gametophyte by mitosis.
Mosses reproduce by spores that are single celled gametophyte which are much older than the seed.
Since both produce haploid gametophythe, the both reproduce by mitosis.
