Prothallium is a tiny, green, heart-shaped structure produced by ferns during their reproductive cycle. It is a haploid gametophyte stage in the fern life cycle. The prothallium is the phase of the fern life cycle where sexual reproduction occurs.
The purpose of the prothallium is to produce and release sperm and eggs, which then fertilize to form a diploid zygote. The prothallium is typically found growing on the forest floor or in moist environments. It releases chemicals that attract sperm, which swim towards the egg for fertilization. Once fertilization occurs, the zygote develops into a diploid sporophyte, which is the fern plant that we commonly recognize.

A prothallium is a small, flat, heart-shaped structure found in ferns and other related plants that belong to the division Pteridophyta.
The purpose of the prothallium is to produce male and female reproductive cells (sperm and eggs) and facilitate the process of fertilization. It acts as a gametophyte generation in the life cycle of ferns and some other plants, which means it produces the gametes required for sexual reproduction.
The prothallium is typically formed by the germination of a spore from the sporophyte generation. It is a temporary structure that exists independently from the parent fern plant. The male and female reproductive organs, called antheridia and archegonia, respectively, develop on the surface of the prothallium. These organs produce sperm and eggs, which, upon fertilization, give rise to a new sporophyte plant.
