Mosses require water to reproduce which is why they struggle to survive in drier climates. Ferns and mosses have a wonderfully interesting way of reproducing. All land plants have alternating generations where one generation (the gametophyte generation) has half the genetic material as the second generation (the sporophyte).

Discuss briefly the following types of aestivation in flowers Liverworts and hornworts are other plants in this group. Ferns reproduce using spores, while mosses reproduce with archegonium. This is the gametophyte phase of ferns. Ferns and mosses reproduce by releasing millions of spores through the air. So it's not just a simple case of mature diploid male fertilizes mature diploid female. The wind carries the pollen to the female cone where the male gametophyte develops further and sends out a pollen tube to reach the egg cell in the female gametophyte.
