In plants exhibiting alternation of generations, the generation which bears asexual spores; -- opposed to gametophyte. It is not clearly differentiated in the life cycle of the lower plants.
diploid life phase that produces haploid spores (asexual reproduction)
n. (Gr. sporo, a seed; phyton, plant) the diploid spore-producing phase in plants with alternation of generations.
in plant life cycles, is the vegetative body that develops by mitotic divisions from the zygote, and when mature produces spore-bearing structures.
The life cycle stage in plants and algae that terminates in meiosis to produce spores
diploid life form of sexually reproducing plants. The dominant form of angiosperms (flowering plants).
A diploid plant or plant structure that produces haploid spores through meiosis.
The spore-bearing generation consisting of seta and capsule.
The diploid sexual-spore-producing generation in the life cycle of plants. The stage in which meiosis occurs. The stage of a plant life cycle that produces spores by meiosis and alternates with the gametophyte stage.
The asexual generation of plants.
(spor´ o fyte) [Gr. spora: seed + phyton: plant] • In plants with alternation of generations, the diploid phase that produces the spores. (Contrast with gametophyte.)
A plant with the diploid number of chromosomes that is produced by those plants that have alternation of generations. The sporophyte gives rise to spores which are haploid and go on to produce the gametophyte generation. In flowering plants, the sporophyte is the dominant generation, while in mosses and liverworts, it is dependant on the gametophyte.
In plants with alternation of generations, it is a plant in the diploid phase that produces spores.
the spore-producing individual or phase in the life cycle of a plant having alternation of generations
the phase of the life history that produces spores.
The diploid (2n) spore-producing phase of the life cycle of an organism exhibiting Alternation of Generations.
the spore producing, diploid (2N) phase of the life cycle; compare to gametophyte
diploid stage of a life cycle (c.f. gametophyte)
The diploid stage in the life cycle of a plant, in species that show alternation of generations, that produces asexual spores.
The diploid, spore-producing generation in plants with alternation of generations. In liverworts, mosses, and hornworts, the sporophyte is completely dependent on the gametophyte. In Lycophytes, ferns, and horsetails, sporophytes and gametophytes are generally independent and free-living. In the seed plants, the sporophyte is the dominant stage in the life cycle, and the gametophytes are highly reduced and dependent on the sporophyte.
The diploid stage of a plant exhibiting alternation of generations. The diploid, spore producing phase of the plant life cycle. PICTURE
(syn. sporophore) The spore-bearing part or generation.
a plant, or phase of a life cycle, that bears the spores formed during the sexual reproductive cycle.
a spore-bearing plant.
The multicellular diploid form in organisms undergoing alternation of generations that results from a union of gametes and that meiotically produces haploid spores that grow into the gametophyte generation.
The individual or generation of a plant exhibiting alternation of generations that bears asexual spores. (compare " Gametophyte".).
the part of a life cycle when the full complement of chromosomes are present.
The diploid stage in the life cycle of an organism undergoing an alternation of generations. The sporophyte is multicellular and develops from a zygote. The mature sporophyte meiotically produces haploid spores that later generate the gametophyte generation.
In plants, a multicellular stage that produces haploid spores by meiosis. What we think of as a plant in everyday speech refers to the sporophyte stage of the plant life cycle.
Produces spores as reproductive bodies.
the diploid, spore-producing, asexual generation in the life cycle of a plant; typically formed by fusion of haploid gametes
The diploid sexual-spore-producing generation in the life cycle of plants that is, the stage in which meiosis occurs.
A sporophyte is the structure of a plant or alga that has a diploid set of chromosomes. It is seen in all plants and in some algae.
