Which stage is the dominant stage in mosses quizlet?
Which stage is the dominant stage in mosses quizlet?
The gametophyte is the dominant stage of the life cycle in mosses; the sporophyte develops on the body of a gametophyte, where it lives for a briefer time than the gametophyte’s life span.
What is the dominant life cycle stage for liverworts and mosses?
In bryophytes (liverworts, hornworts, and mosses), the gametophyte stage is dominant. The leafy green structures we recognize (Figure below) are haploid, and perform most of the photosynthesis.
Which stage is the dominant stage in mosses 3 points?
gametophyte stage
In mosses, the gametophyte stage is the dominant stage. This stage alternates with the sporophyte stage. The green gametophyte stage of mosses…
Which of these is the dominant stage of the alternation of generations for mosses?
gametophyte
In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set). In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant.
Which stage is dominant in bryophyta?
The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle.
What is the life cycle of Hornworts?
Hornworts undergo a life cycle that is called alternation of generations, which means that the plant undergoes different stages. In some of those stages, the plant is haploid and in some, diploid. If you recall, the gametophyte and spore are haploid and the sporophyte and zygote are diploid.
What is the dominant stage?
The dominant phase in the tracheophyte life cycle is the diploid (sporophyte) stage. The gametophytes are very small and cannot exist independent of the parent plant.
Which stage is the dominant stage in gymnosperms?
Answer Expert Verified The dominant stage in gymnosperms is sporophyte.
Which part of the life cycle is dominant in bryophyte?
haploid stage
The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote.
Which generation is dominant in gymnosperms?
sporophyte generation
The gymnosperm life cycle has a dominant sporophyte generation. Both gametophytes and the next generation’s new sporophytes develop on the sporophyte parent plant.
What stage is dominant in gymnosperms?
Sporophyte
Thus, the correct answer is ‘Sporophyte. ‘
What stage is dominant in Ferns?
sporophyte stage
First, all plants undergo an alternation of generations, between a haploid gametophyte stage and a diploid sporophyte stage. In the most primitive plants, like mosses, the gametophyte is dominant (i.e. it’s big and green). In higher plants like ferns and fern allies, the sporophyte stage is dominant.
Which is the dominant stage in a moss?
In mosses, the gametophyte stage is the dominant stage. This stage alternates with the sporophyte stage. The green gametophyte stage of mosses… See full answer below.
What kind of environment do mosses live in?
Mosses are considered a primitive type of plant and are in the division Bryophyta. There are thousands of species of these, and they generally lack true roots, stems, or other vascular tissues. They are often found in a moist environment but can be found in a wide variety of habitats.
Which is the dominant phase of the sporophyte?
> The Sporophyte is the domin… The plant body or the vegetative phase is diploid in pteridophytes, gymnosperms and angiosperms. The reproductive structures like the stobili in pteridophytes, ovules and microsporangium, anther are also diploid.
How are the spores of mosses and ferns dispersed?
Mosses reproduce by spores, which are analogous to the flowering plant’s seed; however, moss spores are single celled and more primitive than the seed. Spores are housed in the brown capsule that sits on the seta. Pieces of the moss body can break off, move by wind or water, and start a new plant if moisture permits.
