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.
Which stage in the alternation of generations life cycle would fern represent?
The Sporophyte life cycle is the dominant stage in Ferns (vascular non-seed plants)
What do ferm and mosses reproduce?
Ferns and mosses reproduce using spores rather than seeds. Both plants have a life cycle that includes a dominant gametophyte stage, which produces gametes for sexual reproduction. In ferns, the sporophyte stage is more prominent, while in mosses, the gametophyte is the dominant stage. Spores are released from sporangia and can grow into new gametophytes under suitable conditions.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
What is the sporophyte stage of ferrns?
The sporophyte stage of ferns is the dominant stage in their life cycle. It is the diploid phase where spore-producing structures called sporangia develop on the underside of the fronds. Spores are released from the sporangia and germinate into a new gametophyte plant.

What is the dominant generation in ferns and how does it contribute to the reproductive cycle of these plants?
The dominant generation in ferns is the sporophyte, which is the larger and more visible stage of the plant. The sporophyte produces spores through meiosis, which then develop into the gametophyte stage. The gametophyte produces gametes (eggs and sperm) through mitosis, which then fuse to form a new sporophyte, completing the reproductive cycle of ferns.
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.

What does moss ferns and liverwort have in common?
They both: use photosynthesis do not produce seeds or flowers use spores to reproduce have a dominant gametophyte stage
What Were the dominant plants in the precambrian?
Ferns
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.

The sporophyte stage of ferns is the dominant stage in their life cycle. It is the diploid phase where spore-producing structures called sporangia develop on the underside of the fronds. Spores are released from the sporangia and germinate into a new gametophyte plant.
Alternation of generation different moss ferns?
The alternation of generations in mosses and ferns involves two distinct life stages: the gametophyte and the sporophyte. In mosses, the dominant life stage is the gametophyte, which is haploid and produces gametes. In contrast, ferns have a more prominent sporophyte stage, which is diploid and produces spores through meiosis. This alternation allows for genetic diversity and adaptation to varying environmental conditions.
Why do ferns have a dominant gametophyte?
Ferns have a dominant gametophyte stage because their life cycle alternates between a haploid gametophyte and a diploid sporophyte. In ferns, the gametophyte is often photosynthetic and independent, allowing it to thrive in various environments, while the sporophyte is typically larger and more complex. This dominance of the gametophyte allows for effective reproduction and dispersal, as it can produce gametes that will develop into new sporophytes. Additionally, the gametophyte's ability to survive in a range of conditions enhances the overall adaptability of ferns.
Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
