In moss, where the sporophyte grows directly out of the top of the gametophyte.
When the gametophyte dies
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.
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.
The sporophyte stage depends on the gameophytestage because the gameophyte stage has a photosynthic stageand because the sporophyte stage lives shortly.
Blade grass, like other flowering plants, primarily exists in the sporophyte stage of its life cycle. The sporophyte is the dominant phase, characterized by the production of seeds and flowers. The gametophyte stage is reduced and typically occurs within the reproductive structures of the sporophyte. Thus, blade grass is predominantly a sporophyte.
SPOROPHYTE
When the gametophyte dies
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.
The sporophyte of a fern, destined to grow to be magnitudes larger than the prothallium, destroys the prothallium as it grows.
A moss sporophyte acquires nutrients through its connection to the gametophyte, which provides it with water and nutrients through a structure called the seta. This allows the sporophyte to grow and develop in its environment.
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.
The gametophyte is responsible for producing gametes, both male and female. When a male gamete fertilizes the female gamete, a zygote, or fertilized cell is created. This zygote matures and grows (through mitosis) into a sporophyte. At this point, the gametophyte has already done its job, and is not needed. Therefore it dies. The sporophyte releases spores, which eventually develop into gametophytes, and the cycle restarts.
Either a Spore or Sori The Rhizome is an underground stem that they grow from. Hope I helped!
Gametophyte-haploid Sporophyte-diploid
Flaggelated asexual spores produced by a protist or early diverging fungi. A zoospore escapes the zygote of an adult diploid sporophyte in an aquatic enviornment, settles, and then uses mitosis to grow into a haploid adult algae or fungi know as a gametophye which produces sexual gametes that fuse together and grow into a diploid sporophyte through meiosis.
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.
Three examples of a sporophyte are Polypodium, mosses, and a pine tree.
