What else can I help you with?
In plant division which one are seedless vascular plants?
I believe it is the gametophyte stage, while the sporophyte stage is much reduced. ( I hope I do not have that backwards, but wolves are my special interest )
The pollen grain replaces what structure in the life cycle of seedless plants?
"Pollination is the transfer of the pollen grain from the anther to the stigma, where the pollen grain germinates, and becomes the mature male gametophyte." Source= Inquiry into Life Lab Manual. Therefore, the answer may be the mature male gametophyte...OR that it replaces a males sperm, depending on what your teacher is looking for. Hope this helps
What is a structure in seedless plants that produces sperm?
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.
What trait do ferns have that mosses do not?
Mosses are non-vascular plants whereas ferns are vascular. In ferns Sporophyte is dominant but in mosses gametophyte is dominant generation. Ferns have definite roots but in mosses leaves and roots are mostly false.
Does seedless plants have pollen?
Yes, seedless plants produce pollen. Pollen is the male reproductive structure responsible for transferring sperm cells to female reproductive structures in plants for fertilization. Seedless plants, such as ferns and mosses, rely on spores for reproduction, but they still produce pollen for this purpose.
In which group of plants are both the sporophyte and gametophyte free- living?
In seedless vascular plants, such as ferns, both the sporophyte and gametophyte stages are free-living. The sporophyte is the dominant stage, while the gametophyte is usually a small, independent structure that produces gametes.
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.
What does gametophyte dominated mean?
Plants have an alternation of generations when they are in the gametophyte stage or the sporophyte stage. Gametes, which is haploid, or spores, which are diploid. Seedless vascular plants can be dominated by a haploid gametophyte stage where they are most of the time.

Which generation is dominate in seedless vascular plants?
Sporophyte is the dominant generation.

What is a plant's lifecycle?
Depends on the plant: If it is a bryophyte, most of the time is spent in the gametophyte stage, until a sperm and egg fertilize. Once that happens the plant goes to the sporophyte stage, where spores are released to create more gametophytes. In seedless vascular plants, such as ferns, the plant still starts in the gametophyte (until fertilization) but the majority of the cycle is spent in the sporophyte stage (release spores to create new gametophytes). Seed bearing vascular plants have both stages at the same time but the sporophyte stage is not seen, all takes place in the flower.
What is a structure in seedless plants that produces sperm?
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.

Seedless plants, such as ferns and mosses, rely on spores for reproduction, but they still produce pollen for this purpose.
The tiny male gametophyte of seed plants that produces sperm?
Yes, It is cool though because in seed plants the gametophyte is microscopic and remains in the sporophyte. It gains extra protection (UV light, Drying out ect) and nutrition. This increases the chance of survival when compared with the free living gametophytes of seedless plants. (awesome evolutionary step that lead to the increased probability of seed production)
Where does meiosis occur in seedless plants?
Meiosis typically occurs in the specialized structures called sporangia or sporophylls in seedless plants. These structures are found on the sporophyte generation of the plant, where meiosis takes place to produce spores.
