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.

What is the difference between spermatophytes and bryophytes?
Spermatophytes are seed-producing plants that include gymnosperms and angiosperms, while bryophytes are non-vascular plants like mosses, liverworts, and hornworts. Spermatophytes have seeds for reproduction and vascular tissues for water and nutrient transport, whereas bryophytes reproduce via spores and lack vascular tissues. Spermatophytes have a dominant sporophyte generation, while bryophytes have a dominant gametophyte generation.
What is the difference between bryophytes and tracheophytes?
The main difference between bryophytes and tracheophytes is that bryophytes are non-vascular plants whereas tracheophytes are vascular plants. Both of them have heteromorphic alternation of generation that means the two generations gametophytes and sporophytes are morphologically as well as cytologically different. in bryophytes gametophyte generation is more prominent in which male and female gametes fuse to each other to form zygote which develops into well protected embryo, while in tracheophytes, sporophytes generation is more dominant and gametophyte generation is very small and inconspicuous.
Which generation is dominant in gymnosperms?
The dominant generation in gymnosperms is the sporophyte generation.
Are bryophytes the simplest group of plant?
Bryophytes are the simplest land plants because they lack vascular tissues and are usually 1 to 2 cm in height and they need water for their reproductioin and they live in damp places and in them gametophyte generation is dominant.
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.
Is the gametophyte the dominant generation?
in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
Why gametophyte is dominant in baryophytes?
In bryophytes, the gametophyte generation is dominant because it is the stage that is more prominent, photosynthetic, and capable of independent growth. This generation develops from spores and produces gametes through mitosis, allowing for sexual reproduction and genetic diversity. The sporophyte, which arises from the fertilization of gametes, is typically dependent on the gametophyte for nutrition and support, making the gametophyte the more prominent and vital stage in the life cycle of bryophytes.

Which generation is dominant in gymnosperms?
The dominant generation in gymnosperms is the sporophyte generation.
Is this true haploid form is dominant of bryophytes?
Yes, in bryophytes, the haploid form is dominant. The life cycle of bryophytes, which includes mosses, liverworts, and hornworts, features a prominent gametophyte stage that is haploid and photosynthetic. The diploid sporophyte is usually smaller, dependent on the gametophyte for nutrition, and remains attached to it for the duration of its life cycle. This distinctive alternation of generations is a key characteristic of bryophytes.
Are bryophytes the simplest group of plant?
Bryophytes are the simplest land plants because they lack vascular tissues and are usually 1 to 2 cm in height and they need water for their reproductioin and they live in damp places and in them gametophyte generation is dominant.
Are bryophytes the only plants having a dominant gametophyte stage in their lifecycle?
Plato: True
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.
Is the gametophyte not free living in bryophytes?
In bryophytes, the gametophyte is the dominant, free-living stage of the life cycle. It is the structure responsible for producing gametes and supporting fertilization. The gametophyte in bryophytes usually grows independently from the sporophyte, which is dependent on the gametophyte for nutrition and support.
What is the terms applies to bryophytes?
Bryophytes are non-vascular plants that lack specialized tissues for conducting water and nutrients. They include mosses, liverworts, and hornworts. These plants reproduce via spores and have a gametophyte-dominant life cycle, where the dominant, independent stage is the haploid gametophyte.
What is dominant generation in the life cycle of a bryophyte?
In the life cycle of a bryophyte, the dominant generation is the gametophyte stage. This is the haploid phase that produces gametes (sperm and eggs) through mitosis. The gametophyte is typically the more visible and longer-lived phase, while the diploid sporophyte, which develops from fertilized eggs, is usually smaller, dependent on the gametophyte, and short-lived. This alternation of generations is a key characteristic of bryophytes.
