What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.
Why don't archegonia and antheridia mature at the same time on a prothallus?
Archegonia and antheridia do not mature at the same time on a prothallus to prevent self-fertilization and promote genetic diversity. By producing mature reproductive structures at different times, the prothallus increases the chances of cross-fertilization with gametes from other individuals.
In a plant's life cycle a spore develops into a stage known as the?
Prothallus/Prothallium
What is shape of prothallus of fern?
flat.heart-shaped membranous structure with numerous rhizoids on its central lower surfaces.
What kind of plant structure does meiosis produce in seedless plants?
Meiosis in seedless plants produces spores, which are haploid reproductive cells that can grow into multicellular haploid organisms called gametophytes. These gametophytes eventually produce gametes for sexual reproduction.
Which of the following plants has a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
Flowering Plants.
What plant reproduces sori and a prothallus?
Ferns reproduce using sori and prothallus.
What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.
How many sporopytes develop from one prothallus?
One sporophyte developes from one prothallus
What plant reproduces using sori and a prothallus?
The plant that reproduces using sori and a prothallus is a fern. Sori are clusters of sporangia where spores are produced, while prothallus is the gametophyte stage in the fern life cycle where fertilization occurs. Ferns have a unique reproductive cycle that involves both sexual and asexual reproduction.
How ferns plant produce?
Through prothallus
The heart-shaped gametpphyte structure in ferns is called what?
prothallus.
What structures do seedless vascular plants have that the seed ones don't have?
Prothallus
What are fern spores grow into heart-shaped plants that produce?
Prothallus
In seedless plants meiosis produces what kind of plants structure?
Prothallus

What is the name to the gametophype generation in fern?
Gametophyte generation of fern is called prothallus.
