The fusion of male and female gametes takes place in the embryo sac. In plants, reproduction takes place in flowers. A flower is the main reproductive organ. The male and female reproductive part of the flower is stamen and pistil respectively.
Where does the fusion of gametes occur?
Because the egg and sperm cells exist as a hemi-protoplast and as protoplasts in the embryo sac, respectively, to allow membrane fusion between gametes, it is possible that gamete fusion can occur around the chalazal surface of the egg cell, except for where it is attached to synergids (Fig. 1A).
Do gametes determine gender?
Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female.
What is the process of fusion of gametes called?
Gametes are mature, haploid cells that develop from germ cells following meiosis, mitosis, and cell differentiation. … During the process of fertilization, a series of reactions triggers the fusion of gametes to produce a diploid cell called a zygote.
What happens after gamete fusion?
After fusion or fertilization these two gametes fused to create a zygote which is diploid (2n) after furthermore changes during this zygote it’ll grow to be a replacement individual. A zygote could be a eukaryotic cell formed by a fertilization event between two gametes.
Is the fusion of gametes?
This fusion of gametes is called fertilisation. Sex cells are also known as gametes. Male gametes are made by male reproductive structures. Female gametes are made by female reproductive structures.
