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
Where in an angiosperm would you find a megasporangium?
In an angiosperm, the megasporangium is found within the ovule, which is located within the ovary of the flower. The ovule is the structure where meiosis occurs to produce the megaspore, which will eventually develop into the female gametophyte.
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
Why can we say that the embryo sac is the female gametophyte of flowering plants?
The embryo sac is considered the female gametophyte in flowering plants because it develops from a megaspore through mitotic divisions and gives rise to the egg cells and other supportive cells necessary for fertilization and seed production. Just like the male gametophyte (pollen grain) produces sperm cells, the embryo sac produces egg cells for sexual reproduction.

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.
How many megaspores die if only four are produced?
If only four megaspores are produced, then three out of the four will typically die. This is because usually only one megaspore develops into a functional female gametophyte, while the others degenerate.
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.
What is the function of the spore of gymnosperms?
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.

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).
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
What is the difference between megasporangia and microsporangia?

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.
