The lifecycle of plants alternates between?
a haploid gametophyte stage and a diploid sporophyte stage..
What is a primary sporophyte?
spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
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.
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 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.
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 is alternation of generation?
It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation. A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte). It once was called hydrogen power. In more simple terms, it is a life cycle in which there is both a multicellular diploid form, and a multicellular haploid form.
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.
Does the fertilized egg in an ovule become the zygote of a new sporophyte?
Yes, the fertilized egg within an ovule develops into a zygote, which is the initial cell of a new sporophyte generation in plants. Following fertilization, the zygote undergoes a series of divisions and developmental processes to form an embryo, which will eventually grow into a mature sporophyte. This process is part of the plant life cycle, which alternates between the sporophyte and gametophyte generations.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
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.
