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.
What else can I help you with?
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.
Why is it advantageous for the antheridia and archegonia to be located on the underside of the prothallus?
Having antheridia and archegonia on the underside of the prothallus protects them from desiccation and mechanical damage, as they are closer to the substrate. This positioning also aids in the dispersal of sperm towards the eggs when water is present, as water carries the sperm to the archegonia.
What is the heart shaped gametophyte called?
Fern spores grow into "Prothallia". The singular is "Prothallium".
In the fern life cycle a spore germinates to form an?
In the fern life cycle, a spore germinates to form a gametophyte. This gametophyte produces male and female gametes through mitosis, which then fuse to form a zygote. The zygote develops into a new sporophyte plant.
What plant reproduces sori and a prothallus?
Ferns reproduce using sori and prothallus.
How many sporopytes develop from one prothallus?
One sporophyte developes from one prothallus

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 forms in the prothallus?
The prothallus, which is the gametophyte of ferns, has several key structures. These include the rhizoids for anchoring and absorption, the archegonia for producing eggs, and the antheridia for producing sperm. Additionally, the prothallus also has chlorophyll-containing cells for photosynthesis.
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.
What is the name to the gametophype generation in fern?
Gametophyte generation of fern is called prothallus.
Is mallic acid found in prothallus of fern?
yes says Krystof jehlicka
