What is the fate of male gamete?

What is the fate of male gametes released in the ovary?

In flowering plants, out of the two male gametes discharged in synergids, one fuses with the egg and other fuses with the secondary or definitive nucleus present in central cell.

What happens to the second male gamete?

Second male gamete joins with two polar cores to shape Endosperm. The ovary of the plant delivers the female ovule, or egg cell.

How are male gametes transferred to females?

When the male ejaculates (when semen leaves the penis), a small amount of semen is deposited into the vagina. Millions of sperm are in this small amount of semen, and they “swim” up from the vagina through the cervix and uterus to meet the egg in the fallopian tube.

What would have been happened if the male and female gametes had been diploid?

If the gametes of the male and female had been diploid then the zygote formed after fusion would have double the chromosomes of the gamete. This means the zygote would have ninety-two chromosomes. In other words, it would be tetraploid.

What are the male gametes female gametes?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

When male gamete fuses with the secondary nucleus?

One of the male gametes fuses with the egg cell to form a zygote(syngamy). The other male gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nucleus (PEN). Because of the involvement of two fusions, this event is termed as double fertilisation, an event unique to angiosperms.

What produces a gamete?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

Where are the gametes produced?

Gametogenesis. Gametes (germ cells) are produced in the gonads. In females, this is called oogenesis and, in males, spermatogenesis.
