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.
In plants meiosis leads directly to the production of what?
Meiosis in plants leads directly to the production of haploid spores, which will eventually develop into gametophytes. These gametophytes will then produce gametes through mitosis, allowing for sexual reproduction to occur.
Plant spore give rise to what?
Plant spores give rise to haploid gametophytes, which then produce gametes through mitosis. These gametes fuse during fertilization to form a diploid zygote, which grows into a new sporophyte plant.
What generation is dominant in ferns and how does it contribute to their reproductive cycle?
The dominant generation in ferns is the sporophyte generation. This generation produces spores through meiosis, which then develop into gametophytes. The gametophytes produce gametes that fuse to form a new sporophyte, completing the reproductive cycle of ferns.
Where are the gametophytes of gymnosperms found?
The gametophytes of gymnosperms are found within the reproductive structures of the plant, such as the male cones for the pollen-producing male gametophytes and the ovules for the egg-producing female gametophytes.
The spores that plants produce develop into?
gametophytes
In seed plants what do female gametophytes produce?
egg
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.
What important structures do gametophytes produce?
Gametophytes typically produce gametes through the process of mitosis. These gametes are necessary for sexual reproduction as they unite to form a zygote, which develops into the sporophyte generation. Additionally, some gametophytes also produce specialized structures such as antheridia and archegonia that house and protect the gametes.
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 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.
How are the Gametophytes of seed plant different from the gametophytes of seedless plants?
Seed plants:produce seeds Seedless plants:don't produce seeds
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.
Is moss homosporous?
Yes, most mosses are homosporous, meaning they produce spores of the same size and type that can develop into either male or female gametophytes. These gametophytes then produce gametes that fertilize to form sporophytes.
When the spores of some plants grow the new plants are called what?
There new plants are called gametophtes
What kind of plant structure does meiosis produce in seedless plants?
Meiosis in seedless plants produces spores, which are haploid reproductive cells that can grow into multicellular haploid organisms called gametophytes. These gametophytes eventually produce gametes for sexual reproduction.
Why are sporophytes taller than gametophytes?
Sporophytes are typically taller than gametophytes because they are the dominant phase in the life cycle of plants, investing more energy in growth and reproduction. Sporophytes produce spores through meiosis, giving rise to new gametophytes, which are usually smaller and shorter-lived in comparison.
