What is true of all seed plants The gametophyte is dominant Seeds are enclosed in a vessel The gametophyte is free living The sporophyte is dominant?
The sporophyte is dominant.
What generation is dominant in both gymnosperms and angiosperms?
gymnosperm- sporophyte angiosperm- sporophyte
What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?
in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.

How do moss and ferns differ?
Ferns are pteridophytes. Mosses are bryophytes. Mosses have rhizoids, simple root like structures, ferns have rhizomes or underground stems. Both ferns and mosses reproduce via spores, produced from the sporophyte and gametes from the gametophyte. Ferns; however, are sporophyte dominant and mosses are gametophyte dominant. The main, most noticeable form of the moss is the gametophyte, a haploid structure. The less obvious moss sporophyte is simply a stalk called a seta and spore capsule. On the other hand the most noticeable part of the fern is the sporophyte, which may be huge in the case of tree ferns like Dicksonia and Alsophila/Cyathea. The very much less conspicuous part of a fern life cycle is the nondominant gametophyte, which takes the form of a cardoid prothallus and produces gametes (sperm cells and egg cells) in archegonia and antheridia. Spores are produced in the spore capsules of mosses. In ferns, whole clusters of spore capsules called sporangia are found huddled in structures called sori (singular sorus) on the underside of the fern fronds. Mosses do not have true leaves. The leaf like structures are haploid and unicellularly thick. Ferns have multicellular, diploid fronds.

What is the dominant generation of Bryophytes?
In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell.http://en.wikipedia.org/wiki/Vascular_plants
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
Which of the following is true of the life cycle of mosses?
a) The growing embryo gives rise to the gametophyte.b) The sporophyte generation is dominant.c)Spores are primarily distributed by water currents.d) The haploid generation grows on the sporophyte generation.e) Antheridia and archegonia are produced by gametophytes.
Which description best fits nonvascular plants?
The gametophyte is dominant and free living; the sporophyte is not free living.
Dominant sporophyte of angiosperms?
No. Only in bryophytes (mosses, hornworts, and liverworts) is the gametophyte dominant. In advanced plants, the sporophyte is dominant. The gametophyte in angiosperms is a tiny part buried w/in the flower. Hope this helps.
What is the sporophyte generation of a conifer?
Sprophyte is dominant in a conifer
