Embryo sac is the female gametophyte of flowering plants. Situated in the flower. It is dependent on the sporophyte (what we call plant) for nutrition. here the gametophyte is reduced and sporophyte is dominant.
In lower plants the female gametophyte is prominent and independent where it can photosynthesize. Usually it is called as a thallus. Here the sporophyte is reduced and the gametophyte is dominant.
What else can I help you with?
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
The megaspore of a conifer will become?
The megaspore of a conifer will become the female gametophyte, which contains the egg cell. This structure is essential for fertilization and seed production in conifers.
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate
What will be the ploidy of the cells of the nucellusMMCthe functional megaspore and female gametophyte?
Nucellus and MMC are and generally diploid and functional megaspore and female gametophyte are haploid in nature.
Where are the antheridia and archegonia found in ferns?
Antheridia, the male reproductive structures, are typically found on the underside of fern leaves. Archegonia, the female reproductive structures, are usually found near the tips of young fern leaves.
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
In angiosperms the male gametophyte is?
The male gametophyte in an angiosperm is the stamen. The female gametophyte in an angiosperm is the pistil.This is completely wrong. The male gametophyte consists of the generative cell and the tube cell in the pollen grain. The female gametophyte is the 7-celled 8 nucleate embryo sac.
The female gametophyte contains how many nuclei?
The female gametophyte typically contains 7 cells and 8 nuclei.
The megaspore of a conifer will become?
The megaspore of a conifer will become the female gametophyte, which contains the egg cell. This structure is essential for fertilization and seed production in conifers.
Name the parts of an angiosperm flower in which development of male and female gametophyte take place?
Parenchyma cells Stamen & pistil
What is the alternate term for the gametophyte in angiosperms?
The alternate term for the gametophyte in angiosperms is the embryo sac. It is the female gametophyte within the ovule that produces the egg cell.
What structure does the male gametophyte become?
In flowering plants, megaspores become the female gametophytes.
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 flowering plants becomes the female gametophyte?
In flowering plants, megaspores become the female gametophytes.
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte.

What will be the ploidy of the cells of the nucellusMMCthe functional megaspore and female gametophyte?
Nucellus and MMC are and generally diploid and functional megaspore and female gametophyte are haploid in nature.
In flowering plant which of these becomes the female gametophyte?
The female gametophyte in a flowering plant is the embryo sac, which is formed within the ovule. It consists of seven cells, including the egg cell which is essential for fertilization to occur.
