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.
What is the surrounding membrane that consists of 8 nuclei called in the flowering female gametophyte?
it is a sporophyte
The type of life cycle seen in plants is called?
alternation of generation
What is alternation of genes?
A reproductive cycle in which a haploid (n) phase (the gametophyte), gives rise to gametes, which after fusion to form a zygote, germinate to produce a diploid (2n) phase (the sporophyte). Spores produced by meiotic division from the sporophyte give rise to new gametophytes, completing the cycle.
In what ways do club mosses and mosses differ from each other?
Club mosses are vascular plants with erect stems that bear spores in club-shaped, cone-like structures. And True mosses are non-vascular plants which have simple leaflike, rootlike, and stem like parts. They're not true leaves, roots, or stems because they lack vascular tissues.
What structure does meiosis occur in bryophyte?
Meiosis occurs in the sporophyte.
Why is the seta and capsule known as the sporophyte generation?
The seta and capsule are known as the sporophyte generation because they are structures that produce spores through meiosis, which will ultimately give rise to the gametophyte generation. The sporophyte generation is diploid, meaning it contains two sets of chromosomes, whereas the gametophyte generation is haploid, containing one set of chromosomes.
What is the dominant phase of the bryophyte life cycle?
Bryophytes or Moss plants life cycle goes with two stages. The two stages are the haploid (gametophyte) and the diploid (sporophyte) which is the dominant stage.
Which structure is part of a sphagum spp reproduction but not part of the fern reproduction?
sporophyte
Is the female pine cone a sporophyte?
A pine tree is generally a Sporophyte - a multicellular, diploid, spore-producing organism. However, the created spores are haploid, and thus begin the gametophyte phase, in which the microspores (pollen) and megaspores (female receptors), will combine back into a gamete, and begin the sporophyte stage again. So, the pine tree is mostly sporophyte, but has very small gametophyte parts that create gametes. They're very small, but they're there.
What is the common name for a bryophyte?
The common name for a bryophyte is moss.
Do maple trees have leaves?
The maple trees that you see are in the sporophyte stage of the plant life cycle. A sporophyte will produce spores which then develop into gametophytes. So, yes, maple trees have spores (if you are talking about the sporophyte stage). The sporophyte stage is part of the life cycle of all land plants.
What is dominant generation in the life cycle of a bryophyte?
In the life cycle of a bryophyte, the dominant generation is the gametophyte stage. This is the haploid phase that produces gametes (sperm and eggs) through mitosis. The gametophyte is typically the more visible and longer-lived phase, while the diploid sporophyte, which develops from fertilized eggs, is usually smaller, dependent on the gametophyte, and short-lived. This alternation of generations is a key characteristic of bryophytes.
Do maple tree leaves have spores?
The maple trees that you see are in the sporophyte stage of the plant life cycle. A sporophyte will produce spores which then develop into gametophytes. So, yes, maple trees have spores (if you are talking about the sporophyte stage). The sporophyte stage is part of the life cycle of all land plants.
In what structure does meiosis occur in bryophytes?
Meiosis in bryophytes occurs in specialized structures called sporangia. These sporangia house the cells that undergo meiosis to produce spores, which are later dispersed and germinate into the gametophyte stage of the bryophyte life cycle.
Rank in order from oldest to youngest fern bryophyte and bacteria?
Bacteria, arising in the Precambrian followed by bryophytes, the simplest land plants of the Silurian and Devonian followed by pteridophytes (ferns), more advanded than bryophytes due to the acquisition of vascular tissue and sporophyte dominance.
What is a plant's lifecycle?
Depends on the plant: If it is a bryophyte, most of the time is spent in the gametophyte stage, until a sperm and egg fertilize. Once that happens the plant goes to the sporophyte stage, where spores are released to create more gametophytes. In seedless vascular plants, such as ferns, the plant still starts in the gametophyte (until fertilization) but the majority of the cycle is spent in the sporophyte stage (release spores to create new gametophytes). Seed bearing vascular plants have both stages at the same time but the sporophyte stage is not seen, all takes place in the flower.
