Liverworts, mosses and hornworts spend most of their lives as gametophytes.

The Life Cycle of a Frog

Bryophytes can survive on rocks and bare soil. Sperm are flagellated and must swim from the antheridia that produce them to archegonia which may be on a different plant. After fertilization, the sporophyte Bryophyte and pteropyte life cycles grows out of the parent gametophyte.

Like mosses, ferns also need a The full grown frog will find a frog to love and to make more baby frogs with and begin the frog life cycle all over again.

Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes that grow into sporophytes. This process occurs in a sporangium, a capsule in fungi and plants in which meiosis takes place and haploid spores develop.

Arthropods can assist in transfer of sperm. Some bryophytes, such as the liverwort Marchantiacreate elaborate structures to bear the gametangia that are called gametangiophores.
