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

How many cells are produced in males and females in meiosis?
there are 1001 cell produced in male and females meiosis During meiosis one microspore mother cell in the male results in to four microspores after meiosis; so is the case with megaspore mother cell also in females but out of four megaspores only one is functional and the degerating three megaspores nourish the developing one.
Were is pollen made?
Gymnosperms are heterosporous, producing microspores that develop into pollen grains and megaspores that are retained in an ovule. After fertilization (joining of the micro- and megaspore), the resulting embryo, along with other cells comprising the ovule, develops into a seed. The seed is a sporophyte resting stage.
Is a stamen the site where microspores are produced?
Yes
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
What is the difference between ontogeny and phylogeny?
answer difference between ontogeny and phylogeny?
Are all spores in the same sporangium similar?
no selaginella has megaspores and microspores
The result of meiosis in angiosperms is the production of?
for Plato its a answered by Brandy :)
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
Compare the male and female spores of a conifer?
The female spores of a conifer are called megaspores or macrospores. Megaspores develop into a female gametophyte, producing egg cells. Male spores of a conifer are called microspores and are formed from meiosis. Microspores develop into the male gametophyte, which produces sperm cells.
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
Haploid reproductive cells are called?
The four cells formed as a result of meiosis are called daughter cells.
What is the ploidy level of the micropyle?
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
What are the similarities and differences between cones and flowers?
they are similar because they both have seeds and sharp hair
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 staminate and ovulate cones?
A staminate cone contains the male reproductive structures that produce microspores.An ovulate cone contains the female reproductive structures that produce megaspores.
