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.

Is a sporophyte or gametophyte embryo in a seed?
In a seed, it is the sporophyte embryo that is present. The sporophyte is the diploid generation that develops from the fertilization of gametes, while the gametophyte generation is typically reduced and dependent on the sporophyte in seed plants. Thus, the seed contains the developing sporophyte embryo, which will grow into the mature plant.
Is sporophyte dominant in seed plants?
Yes, sporophytes are the dominant generation in seed plants. In these plants, the sporophyte is the larger, more complex structure that carries out photosynthesis and is responsible for reproduction. The gametophyte generation is reduced and often dependent on the sporophyte for nutrients and protection. This shift to a dominant sporophyte is a key characteristic of seed plants, distinguishing them from other plant groups like mosses, where the gametophyte is more prominent.
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.
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.
How have the sporophyte and gametophyte changed as plants have evolved?
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.
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.
Is a sporophyte or gametophyte embryo in a seed?
In a seed, it is the sporophyte embryo that is present. The sporophyte is the diploid generation that develops from the fertilization of gametes, while the gametophyte generation is typically reduced and dependent on the sporophyte in seed plants. Thus, the seed contains the developing sporophyte embryo, which will grow into the mature plant.
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.
Is sporophyte dominant in seed plants?
Yes, sporophytes are the dominant generation in seed plants. In these plants, the sporophyte is the larger, more complex structure that carries out photosynthesis and is responsible for reproduction. The gametophyte generation is reduced and often dependent on the sporophyte for nutrients and protection. This shift to a dominant sporophyte is a key characteristic of seed plants, distinguishing them from other plant groups like mosses, where the gametophyte is more prominent.
Nonvascular plants are the only plant division in which the gametophyte stage is?
The dominant stage of the life cycle in nonvascular plants. It is larger and longer-lived than the sporophyte stage, which is dependent on the gametophyte for nutrition.
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 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.
How does the sporophyte generation of a plant differ from a gametophyte 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.
When a plants life cycle alternates between a sporophyte and gametophyte?
photosynthesis
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
