The fern life cycle and moss life cycle are similar in that they have alternation between sporophyte and gametophyte stages and that both rely on layers of water so that their sperm can swim from one...
The life cycle of the fern Ceratopteris richardii. From sporophyte to spore germination. When we think of ferns, we probably imagine something similar to the Boston ferns that we see for sale in local grocery stores and nurseries.
