Fern spores grow into "Prothallia". The singular is "Prothallium".
sporophyte
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 small, greenish heart-shaped structure or gametophyte (n-haploid) of a fern that produces the male and female gametes for fertilization and spore formation which leads to the development of the sporophyte generation--(2n-diploid) -->the plant you see above ground is the sporophyte generation.
Ants have a unique feature called a "heart-shaped abdomen" that sets them apart from other insects.
The two stages of a moss life cycle are the gametophyte stage and the sporophyte stage. The gametophyte is the dominant and photosynthetic stage, while the sporophyte is short-lived and dependent on the gametophyte for nutrients.
Gametophyte.
The gametophyte of a fern is a small, independent plant that produces gametes (eggs and sperm). This stage in the fern life cycle is usually heart-shaped and photosynthetic, and it is typically found on the underside of leaves in damp environments. The gametophyte is responsible for producing the sperm and egg that will fuse to form a new sporophyte plant.

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 fern gametophyte is nutritionally known as a photosynthetic organism. It is typically a small, heart-shaped structure that produces its own food through photosynthesis, using light energy to convert carbon dioxide and water into glucose and oxygen. This ability allows the gametophyte to sustain itself until it can develop into a mature sporophyte.
flat.heart-shaped membranous structure with numerous rhizoids on its central lower surfaces.
The structure that holds antheridia and archegonia in ferns is called the gametophyte. It is a small, heart-shaped structure that develops on the underside of the fern frond. Antheridia produce sperm cells, while archegonia produce egg cells for sexual reproduction in ferns.
Pteridophytes reproduce through spores, which are produced in structures called sporangia. The spores are released into the environment and eventually germinate to form a small, heart-shaped structure called a gametophyte. The gametophyte produces both male and female gametes, which combine to form a fertilized egg that grows into a new sporophyte plant.

A spore grows into a heart shaped gametophyte. The gametophytes produces sex cells that unite to form a zygote. The zygote grows into a spore producing sporophyte.
something heart shaped is considered Cardiomorphic, but there is no proper name for the heart, it is always called the heart.
This is a disruptting website, no help at all. This was a living nightmare, trying to find these inpaticular answers. If i were the creators of this "Wiki" website, i'd improve just about everything. Thank you for your time out of your day to read this answer. K bye.(:Edited answer:A small green heart-shaped gametophyte represent the gametophytic generation of many pteridophytes such as Lycopodium, Equisetum and many ferns. The male and female sex organs are produced in the form of anthredia and archegonia for sexual reproduction.
