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.

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.
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.
The dominant generation in gymnosperms is the sporophyte generation.
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.
In ferns, the dominant generation is the sporophyte.
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

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.
In ferns, the dominant generation is the sporophyte.
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.
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.
The main plant body is gametophytic as in case of Bryophytes
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.
Meiosis in bryophytes, such as mosses and liverworts, occurs within the sporangium or capsule located on the sporophyte generation. The sporangium produces spores through meiosis, and these spores ultimately develop into the gametophyte generation.
