What is the dominant generation in gymnosperms and how does it contribute to the reproductive cycle of these plants?
The dominant generation in gymnosperms is the sporophyte, which produces spores through meiosis. These spores develop into gametophytes, which produce gametes through mitosis. The gametes then fuse to form a zygote, which develops into a new sporophyte, completing the reproductive cycle of gymnosperms.
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.
What plant group is characterized by dominant sporophyte vascular tissues and seeds exposed on cones?
The plant group characterized by dominant sporophyte vascular tissues and seeds exposed on cones is the gymnosperms. This group includes plants like conifers, cycads, and ginkgo trees. Gymnosperms do not produce flowers and their seeds are not enclosed within a fruit.
What generation is dominant in moss?
The dominant generation in mosses is the gametophyte generation. This is the photosynthetic, leafy structure that produces gametes for sexual reproduction. The sporophyte generation in mosses is much smaller and dependent on the gametophyte for nutrients.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
What generation is dominant in both gymnosperms and angiosperms?
The dominant generation in gymnosperms is the sporophyte generation, while in angiosperms it is also the sporophyte generation. The sporophyte generation produces the structures that we commonly recognize as trees, shrubs, and flowers in plants.

What was the dominant plant group at the time dinosaurs were dominant?
Gymnosperms
What is the sporophyte generation in gymnosperms?
In gymnosperms, the sporophyte generation is the dominant and most recognizable stage of the plant life cycle. It is diploid, meaning it has two sets of chromosomes, and is responsible for producing spores through meiosis in structures called sporangia. These spores develop into the gametophyte generation, which is usually reduced and dependent on the sporophyte for nutrition. Overall, the sporophyte stage is crucial for the growth and reproduction of gymnosperms, as it produces the seeds that ensure the continuation of the species.
What were the dominant trees of the mesozoic era?
cycads
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
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.

What description best fits gymnosperms?
The sporophyte is dominant and free living. The gametophyte is not free living.
What were dominant organisms living in the Cretaceous?
dinosaurs among animals on land and gymnosperms among plants
How is the alternation of generations the same and how is it different between angiosperms and gymnosperms?
Alternation of generations is the same in all plants in the sense that during sexual reproduction gametophytic generation alters with the sporophytic generation. In angiosperms and gymnosperms the only difference is the presence of embryo sac in the ovule in place of archegonium in gymnosperms. Also double fertilization takes place in angiosperms to have sporophytic endosperm, which remains gametophytic in gymnosperms.
