What is the dominant generation in ferns and how does it contribute to the reproductive cycle of these plants?
The dominant generation in ferns is the sporophyte, which is the larger and more visible stage of the plant. The sporophyte produces spores through meiosis, which then develop into the gametophyte stage. The gametophyte produces gametes (eggs and sperm) through mitosis, which then fuse to form a new sporophyte, completing the reproductive cycle of ferns.

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.
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.
As land plants evolved what generation become more dominant A Gametophyte B Sporophyte C both D neither?
In lower plants gametophytic generation was dominant and as the evolution progressed the gametophytic generation became progressively reduced and ultimately became dependent on sporophytic generation. Thus as the evolution progressed sporophyte become more dominant.
Which generation in seed plants is most obvious?
The sporophyte generation is the most obvious in seed plants. This generation is the dominant phase and is the one that is most readily visible in the form of the mature plant.
What sporophyte produce?
Sporophytes produce spores through a process called sporogenesis. Spores are reproductive cells that develop into new individuals in plants, fungi, and some algae. The sporophyte generation is the dominant phase in the life cycle of most land plants.

What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
Which generation is dominate in seedless vascular plants?
Sporophyte is the dominant generation.
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.
Which plant phyla have a dominant sporophyte generation?
In the plant kingdom, the phyla that have a dominant sporophyte generation include the Angiosperms (flowering plants) and Gymnosperms (non-flowering seed plants). Additionally, the vascular plants, such as Ferns (Pteridophyta), also exhibit a dominant sporophyte stage, although the gametophyte is more independent compared to those in non-vascular plants. In contrast, in non-vascular plants like Mosses (Bryophyta), the gametophyte generation is dominant.
What is a primary sporophyte?
spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
As land plants evolved what generation become more dominant A Gametophyte B Sporophyte C both D neither?
In lower plants gametophytic generation was dominant and as the evolution progressed the gametophytic generation became progressively reduced and ultimately became dependent on sporophytic generation. Thus as the evolution progressed sporophyte become more dominant.
What did mendell hypothesize about first generation plants?
Mendel hypothesized that first-generation plants, when crossed, would display a dominant trait in their offspring. He observed that when he crossed purebred plants with contrasting traits, such as tall and short pea plants, the resulting first-generation (F1) plants exhibited only the dominant trait. This led him to propose the concept of dominance in inheritance, suggesting that some traits mask the expression of others in the presence of a dominant allele.
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.
Why were all of mendels first generation plants tall?
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
When a first generation plant self pollinates what is the ratio of the dominant to recessive traits in the second generation plants?
1:3
Which generation in seed plants is most obvious?
The sporophyte generation is the most obvious in seed plants. This generation is the dominant phase and is the one that is most readily visible in the form of the mature plant.
