How are the Gametophytes of seed plant different from the gametophytes of seedless plants?
Seed plants:produce seeds Seedless plants:don't produce seeds
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
What advantage do gametophytes that are either male or female have over gametophytes with both male and female structures?
The gametophyte will not fertilize its own egg.This increase the chance of offsprings will have new combination of genes
What plants produce separate male and female cones that produce microspores and megaspores that develop into male and female gametophytes?
All the cyacads and conifers
How does the haploid form of Ulva switch to its diploid form?
Gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote.
How are the Gametophytes of seed plant different from the gametophytes of seedless plants?
Seed plants:produce seeds Seedless plants:don't produce seeds
The spores that plants produce develop into?
gametophytes
The gametophytes of gymnosperms are found inside reproductive structures called?
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
In seed plants what do female gametophytes produce?
egg
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
Where does megasporangia take place?
Megasporangia are structures that produce megaspores, which are involved in the formation of female gametophytes in seed-producing plants such as gymnosperms and angiosperms. Megasporangia are typically located within the ovules of the plant's reproductive structures, where they develop into megagametophytes during the process of seed formation.

The gametophyte will not fertilize its own egg.This increase the chance of offsprings will have new combination of genes

How does the haploid form of Ulva switch to its diploid form?
Gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote.
What is the main job of the stamen?
Stamen produce microspores which create pollen grains that contain male gametophytes.
What is the important functions that leaves perform?
Leaves are structures that takes the sun's energy to produce chemical energy
