What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?

in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.


Structure that holds antheridia and archegonia in ferns?

The antheridia and archegonia of a fern are located on the prothallus, which is heart-shaped. The prothallus is anchored to the soil by rhizoids.


Are the cells of fern that you see haploid or diploid?

The typical "fern" plant the, sporophyte, is diploid.


What is the life span of a fern?

Ferns are vascular plants differing from the more primitive lycophytes by having true leaves (megaphylls). They differ from seed plants (gymnosperms and angiosperms) in their mode of reproduction - lacking flowers and seeds. Like all other vascular plants, they have a life cycle referred to as alternation of generations, characterized by a diploid sporophytic and a haploid gametophytic phase. Unlike the gymnosperms and angiosperms, the ferns' gametophyte is a free-living organism. Life cycle of a typical fern: # A sporophyte (diploid) phase produces haploid spores by meiosis; # A spore grows by mitosis into a gametophyte, which typically consists of a photosynthetic prothallus # The gametophyte produces gametes (often both sperm and eggs on the same prothallus) by mitosis # A mobile, flagellate sperm fertilizes an egg that remains attached to the prothallus # The fertilized egg is now a diploid zygote and grows by mitosis into a sporophyte (the typical "fern" plant).


How are the fern sporophyte and gametophyte stage the same?

In reference to the sporophyte and gametophyte, are the stages of the plant's life cycle thus being the same.

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.
