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.
What happens to the prothallus as the embryo transforms into the sporophyte?
As the embryo develops into the sporophyte, the prothallus, which is the gametophyte stage of ferns, begins to degenerate. The sporophyte, which is the diploid generation, relies on the prothallus for initial nutrients and support before it becomes independent. Eventually, the prothallus will die off as the mature sporophyte establishes itself and starts to photosynthesize and grow on its own. Thus, the prothallus serves a temporary role in the life cycle of ferns.
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.
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.

How many sporopytes develop from one prothallus?
One sporophyte developes from one prothallus

What is the prothallus of a fern?
The prothallus of a fern is a small, heart-shaped, gametophyte stage in the life cycle of ferns. It typically forms from a germinated spore and is photosynthetic, allowing it to produce energy while also developing structures for sexual reproduction. The prothallus contains both male and female reproductive organs, enabling it to produce sperm and eggs. This stage is crucial for the fertilization process, leading to the development of the sporophyte generation, which is the more commonly recognized fern plant.
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.
