heart shaped
A fern prothallium is heart shaped.
The prothallium of ferns is typically flat and heart-shaped, with a thin and delicate structure. It is the gametophyte stage in the life cycle of a fern that produces the reproductive structures.
The sporophyte of a fern, destined to grow to be magnitudes larger than the prothallium, destroys the prothallium as it grows.
The prothallium is the gametophyte stage in the life cycle of ferns. Its main function is to produce gametes (eggs and sperm) through mitosis, which will eventually lead to fertilization and the formation of a new sporophyte plant.
Prothallus/Prothallium
Prothallium is the name given to the gametophyte generation in ferns. Another term given to these species of ferns is prothallus.
The heart-shaped gametophyte in ferns is called a prothallus. It is a small, flat structure that produces the sexual organs necessary for fertilization to occur.
