Ovarian structure consisting of a developing egg surround by one or more layer of follicle cells. The follicle is the single layer. More than one layer it would be a granulosa cell.
A pheromone that eusporangiate ferns release induce surrounding plants sexual structures to develop. It is a mechanism to induce cross-fertilization.
The gametes of a male animal are produced in the testes, and the gametes of a female animal are produced in the ovaries.They are developed in these gonads from specialized cells called germ cells.
unisex gametes
Male gametes are sperm and female gametes are eggs
meiosis is the process by which gametes are formed
gametangia
The principal cells that the human ovaries produce are the Graafian Follicles.An infant ovary produces the primordial ovum.Pre-Puberty Follicle grows and changes during the Post Puberty phase.Adult ovary produces primary follicles that undergo change as per the ovulatory cycle.Aging ovary shows senile atrophy.Primary follicles undergo changes during the ovulatory cycle.Hence, you findRipening folliceMature Graafian follicle,Ruptured follicle is the Corpus hemorrhagicumOvumMature Corpus Luteum,Corpus Luteum of Pregnancy,Involuting Corpus Luteum.Dr. Ashok KopardayMedical Consultant

While a man continues making new sperm his entire life, a woman is born with all the ova she will ever have. Each cycle several ova are incapsulated in follicles - the first one to mature or ripen will burst from the follicle - this is called ovulation.
A spore. The gametophyte makes gametes, which fertilize to form a zygote. That zygote develops into a sporophyte, which makes spores through meiosis. Those spores will then develop into the gametophyte.
The gametes of a male animal are produced in the testes, and the gametes of a female animal are produced in the ovaries.They are developed in these gonads from specialized cells called germ cells.
No, males do not produce gametes faster than females. In fact, females typically produce a finite number of eggs during their lifetime, whereas males continuously produce sperm throughout their reproductive years. However, the rate of production may vary between individuals.
Follicle stimulating hormone stimulates the gonads to produce gametes. It is sometimes abbreviated FSH.
Yes they are, zygotes themselves are the product of fusion between two haploid gametes. These gametes fuse in order to develop into a multicellular structure, which they are unable to do unless they fuse. The product of their fusion is a zygote which is able to develop into a multicellular structure.
The male gamete - spermatozoon and the female gamete - ovum.
The stamen produces pollen grains, which house the gametes (sex cells) necessary for reproduction. The anther is the location within the stamen where the gametes are manufactured/created. Pollen grains vary in shape, size and surface structures depending on the type of flower that produces them.
