The gametophyte has become smaller, and the sporophyte has become larger.
To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.

In which group of plants are both the sporophyte and gametophyte free- living?
In seedless vascular plants, such as ferns, both the sporophyte and gametophyte stages are free-living. The sporophyte is the dominant stage, while the gametophyte is usually a small, independent structure that produces gametes.
The life cycle of nonvascular plants includes an alternation of generations between a?
The life cycle of nonvascular plants includes an alternation of generations between a gametophyte and a sporophyte. The gametophyte generation produces gametes (eggs and sperm) through mitosis, which then fuse to form a zygote that develops into the sporophyte generation through mitosis. The sporophyte produces spores through meiosis that develop into new gametophytes.
During the life cycle of a plant gametophyte is to n as sporophyte is to?
During the life cycle of a plant, gametophyte is to n as sporophyte is to 2n. Gametophyte produces haploid gametes through mitosis, which fuse during fertilization to form a diploid zygote that develops into a sporophyte through mitosis.
How does the gametophyte generation of a plant differ from the sporophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
In which group of plants are both the sporophyte and gametophyte free-living?
In ferns, both the sporophyte (diploid) and gametophyte (haploid) are independent and free-living stages in the life cycle. The sporophyte is the leafy plant we typically see, while the gametophyte is a small, independent structure that produces gametes.
The gametophyte in seed plants is dependent on or independent of the sporophyte?
In seed plants, the gametophyte is dependent on the sporophyte. The gametophyte is significantly reduced in size and typically exists within the tissues of the sporophyte, relying on it for nutrients and protection. This dependence is a key characteristic of seed plants, distinguishing them from non-seed plants where the gametophyte is more independent.
In which group of plants are both the sporophyte and gametophyte free- living?
In seedless vascular plants, such as ferns, both the sporophyte and gametophyte stages are free-living. The sporophyte is the dominant stage, while the gametophyte is usually a small, independent structure that produces gametes.
What is true of all seed plants The gametophyte is dominant Seeds are enclosed in a vessel The gametophyte is free living The sporophyte is dominant?
The sporophyte is dominant.

What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
When a plants life cycle alternates between a sporophyte and gametophyte?
photosynthesis
The life cycle of nonvascular plants includes an alternation of generations between a?
The life cycle of nonvascular plants includes an alternation of generations between a gametophyte and a sporophyte. The gametophyte generation produces gametes (eggs and sperm) through mitosis, which then fuse to form a zygote that develops into the sporophyte generation through mitosis. The sporophyte produces spores through meiosis that develop into new gametophytes.
What is the difference between sporophyte and gametophyte?
Sporophyte is the diploid (2n) stage in the life cycle of plants that produces spores through meiosis, while gametophyte is the haploid (n) stage that produces gametes through mitosis. Sporophyte generation is dominant in vascular plants, while gametophyte generation is dominant in non-vascular plants like mosses and liverworts.
Do gametophyte live independently of the sporophyte?
Yes, gametophytes can live independently of the sporophyte in certain plant groups, particularly in non-vascular plants like mosses. In these cases, the gametophyte is the dominant life stage, photosynthetic, and capable of surviving and reproducing on its own. However, in vascular plants, the sporophyte is the dominant phase, and the gametophyte is usually reduced and dependent on the sporophyte for nutrition and support.
Do vascular seedless plants have a small gametophyte that is in the reproductive structure of the sporophyte?
Yes, in vascular seedless plants, such as ferns, the gametophyte is typically small and independent, but it is also often found in close association with the sporophyte's reproductive structures. The sporophyte generation is the dominant phase and is usually larger and more complex. The gametophyte produces gametes that fertilize to form the new sporophyte, completing the life cycle. However, the gametophyte itself is not housed within the sporophyte; rather, it exists separately, though in proximity to the sporophyte's reproductive organs.
During the life cycle of a plant gametophyte is to n as sporophyte is to?
During the life cycle of a plant, gametophyte is to n as sporophyte is to 2n. Gametophyte produces haploid gametes through mitosis, which fuse during fertilization to form a diploid zygote that develops into a sporophyte through mitosis.
Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
