What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
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 were the dominant plant form during the Paleozoic Era?
Ferns
What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
ferns.
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.
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
Compare and contrast the nutritional needs of the gametophyte and the sporophyte of mosses and spore-bearing vascular plants and seed-bearing vascular plants?
The gametophyte of moss is the dominant structure

What were the dominant plant form during the Paleozoic Era?
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.
What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
ferns.
What stage of the fern life cycle is dominant?
The diploid sporophyte stage of the fern cycle is dominant. In seed plants, the opposite is true; the haploid gametophyte stage is dominant for these.
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.
Is the gametophyte stage the dominant stage in a gymnosperms life cycle?
no
What is the dominant stage of liverworts?
The answer is gametophyte.
