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
The megaspore of a conifer will become?
female gametophyte...
What is the difference between microspores and megaspores?
microspores are the male gametes whilst megaspore are the female gametes. megaspore also known as megaspore mother cellor megasporocyte. it placed in female cone in the gumnosperm while the microspores placed in the male cone
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
What are megaspores?
They form inside ovules and stayed attached to a parent plant, inside the mass they give rise to a female gametophyte that has an egg cell.

In flowering plant which of these becomes the female gametophyte?
In flowering plants, the megaspore becomes the female gametophyte. It is the larger meiospore produced in heterosporous plants, and is the embryonic sac of a flower.
WHAT IS THE FUNCTION OF THE GYMNOSPERM SPORE?
The gymnosperms produce megaspores and microspores. A microspore is the male spore and megaspore is the large female spore. The microspore undergoes mitosis to produce the multicellular male gametophyte. These male gametophytes are the pollen grains that are contained inside short pollen cones. The megaspore is the large female spore that undergoes mitosis to produce the multicellular female gametophyte that is housed in a large female cone.
What is the function of the spore of gymnosperms?
The function of the spore in gymnosperms is to serve as a reproductive structure that can develop into a gametophyte. The spore undergoes mitotic division to produce a multicellular gametophyte, which then produces the gametes (sperm or eggs). The fusion of these gametes gives rise to the development of the next generation of gymnosperms.
Contrast microspores and megaspores?
Microspore = male gamete (n)Megaspore = female gamete (n) Micro develops in the anther and undergoes mitosis to create pollenMega develops in the ovule, retained in ovary, and undergoes mitosis to create female gametophyte (ultimately, an egg).
What is the difference between megasporangia and microsporangia?
feature mega micro size large small produce megaspore, microspores female gametophyte male gametophyte no.pf spores 4 megaspores numerous microspores
What is the difference between microspores and megaspores?
microspores are the male gametes whilst megaspore are the female gametes. megaspore also known as megaspore mother cellor megasporocyte. it placed in female cone in the gumnosperm while the microspores placed in the male cone
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.
What are megaspores?
They form inside ovules and stayed attached to a parent plant, inside the mass they give rise to a female gametophyte that has an egg cell.
What do gametophytes produce?
Gametophytes go through mitosis to create gametes (pollen in male gametophyte and egg in female gametophyte)
