Lifecycle of a Fern: Spore Release to Fertilization

Explore the fascinating lifecycle of a fern through spore release, gametophyte growth, fertilization, and the formation of zygotes. Witness key stages such as haploid and diploid development, the journey of sperm to the egg, and the crucial role of rain in reproduction. From the release of spores to the development of the adult sporophyte, each step is essential in the fern's reproductive cycle.
