What else can I help you with?
Are the male and female gametophytes separate plants or part of the same plant?
Male and Female gametophytes are in separate plants
What plants produce separate male and female cones that produce microspores and megaspores that develop into male and female gametophytes?
Gymnosperms, such as pine trees, produce separate male and female cones that produce microspores and megaspores. These microspores and megaspores develop into male and female gametophytes, which contain the sperm and egg cells for reproduction.
Do vascular plants produce antheridia and archegonia on the same gametophyte?
Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
Is the gametophyte the dominant generation?
in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Gametophytes are found in?
Depends if you are talking about animals or plants. Plants: male gametophytes (pollen grains) are found in the anther(microsprangium), female ovules are found in the ovary (megasporangium). Animals: Generally male found in the testes and female gametophyes in the ovaries
What contains the plant sperm?
The plant sperm is contained within the pollen grains produced by the anther of a flower. Pollen grains are the male gametophytes of plants and contain the male reproductive cells that will fertilize the female ovule.
What are male gametophytes called?
Male gametophytes of seed-producing plants are called pollen grains. These are the structures that produce the male gametes, known as sperm cells, which are required for fertilization to occur. Pollen grains are dispersed through the air or by insects to reach the female reproductive structures of plants.
What structure does the male gametophyte become?
In flowering plants, megaspores become the female gametophytes.
Are microspores and megaspores produced by mitosis or meiosis?
Microspores and megaspores are produced by meiosis. In plants, microspores develop into male gametophytes (pollen), while megaspores develop into female gametophytes (embryo sacs). This process occurs in the reproductive structures of seed plants, where diploid sporophytes undergo meiosis to produce these haploid spores.
Does marijuana reproduce?
Yes there is male and female plants. Female plants produce the bud and male plants produce pollen sacs when the pollen germinates with the female plant it produces seeds.
