Do moss and fern have dominant gametophytes and small sporopytes?
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.
In mosses why is the sporophyte stage dependent on the gametophyte stage?
in mosses why is the sporophyte stage dependent on the gametophyte stage
Why does the sporophyte of mosses remain attached to the gametophyte?
Because the sporophyte grows out of the gametophyte.
In an angiosperms in the gametophyte dominate?
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 characteristic do ferns have that mosses dont?
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 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 is female gametophyte?
Embryo sac is the female gametophyte of flowering plants. Situated in the flower. It is dependent on the sporophyte (what we call plant) for nutrition. here the gametophyte is reduced and sporophyte is dominant. In lower plants the female gametophyte is prominent and independent where it can photosynthesize. Usually it is called as a thallus. Here the sporophyte is reduced and the gametophyte is dominant.
Compare and contrast the gametophyte plant of the moss with the gametophyte plant of the fern?
The gametophyte of moss is the dominant structure. The sporophyte of ferns is the dominant structure.
Do ferns and mosses reproduce by spores?
Yes the spores are like seeds. They drop off of a fern and onto the ground and sooner or later they sprout and makes a new fern. Spores are not like seeds. They lack a seed coat, endosperm and preformed embryonic parts. In addition spores give rise to the gametophyte generation and seeds give rise to the sporophyte generation. Ferns and mosses do both reproduce by using spores BUT mosses have a reduced almost parasitic…
How do ferns and mosses 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…
Why the sporophyte stage in mosses is dependent on the gametophyte stage?
The sporophyte stage depends on the gameophyte stage because the gameophyte stage has a photosynthic stage and because the sporophyte stage lives shortly.
How does the gametophyte generation of a plant differ from the sporophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
Which stage is the dominant stage in mosses?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.
Compare and contrast moss and fern sporophytes?
The moss sporophyte, a stock and capsule, is dependent on the gametophyte, which is the dominant generation. The fern sporophyte, the leafy frond, is independent and the dominant generation.

How have the sporophyte and gametophyte changed as plants have evolved?
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
Which stage is the main stage of moss sporophyte or gametophyte?
Gametophyte is the main stage in moss and sporophyte is dependent on gametophyte.

Compare and contrast the nutritional needs of the gametophyte and the sporophyte of mosses and spore-bearing vascular plants and seed-bearing vascular plants?How does the sporophyte generation of a plant differ from the gametophyte generation?
The sporophyte generation carries its chromosomes as doubles. .. The spores then develop into the gametophyte generation. In most plants, the gametophyte is tiny compared to the sporophyte. As its name implies, the gametophyte generationproduces sex cells - sperm and eggs.
What are some adaptations of mosses?
They are divided into two parts the sporophyte and gametophyte gametophyte which is the lower part of the moss is made up of rhizoids which absorbs water and mineral salts.However the whole gametophyte can absorb water from any part of the plant.The sporophyte consists of the foot which connects its to the gametophyte.. The seta which has elongated cells that help to hold the capsule high up so that it is able to absorb light…

Tv tuner card software. In reference to the sporophyte and gametophyte, are the stages of the plant's life cycle thus being the same.
Mosses have a one or two step life cycle?
Moss has a two-step life cycle that is more appropriately called alternation of generations. In this process a diploid sporophyte produces a haploid diplophyte that then recombines sexually with another gametophyte to produce a sporophyte.

Sporophyte Vs GametophyteAs land plants evolved what generation become more dominant A Gametophyte B Sporophyte C both D neither?
In lower plants gametophytic generation was dominant and as the evolution progressed the gametophytic generation became progressively reduced and ultimately became dependent on sporophytic generation. Thus as the evolution progressed sporophyte become more dominant.
What are the two stages of plant life?
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization…
