Double Fertilization In Plants. 23 rows double fertilization in angiosperms is a process where a zygote and endosperm are formed in. Double fertilization is a major characteristic of flowering plants.
It is commonly seen in flowering plants (or angiosperms). The pollen tube cell grows into a pollen tube through which the generative cell travels. In this process, two male gametes fuse with one female gamete wherein one male gamete fertilizes the egg to form a zygote, whereas the other fuses with two polar nuclei to form endosperm.
It gives rise to a diploid zygote or oosphere. Two products are obtained as a result of double fertilization. One fuses with an egg to form the zygote, and the other fuses with one or more polar nuclei in the female gametophyte (megagametophyte, or also “embryo sac”) to form an… read more

One sperm nucleus unites with the egg to form the diploid zygote, from which the embryo develops. Discovery, study methods and mechanisms. Each pollen grain produces two sperm;
The Pollen Tube Cell Grows Into A Pollen Tube Through Which The Generative Cell Travels.
One of the male gametes fertilizes the egg resulting in the formation of a zygote and the other unites with 2 polar nuclei for the formation of an endosperm. In the phenomena, one female gamete unites with two male gametes. The microspores, or the pollen, contain two cells:
Double Fertilization Is A Complex Process Of The Fusion Of Haploid Male Gametes With The Haploid Egg Nucleus To Form The Diploid Zygote And The Fusion Of Another Haploid Male Gamete With The Diploid Polar Nucleus To Form The Triploid Primary Endosperm Nucleus.
Double fertilization is the fertilization procedure feature of flowering plants. Double fertilization is a chief trait of flowering plants. The double fertilization of flowering plants was discovered a century ago.
The Other Sperm Unites With The Two Nuclei Located In A Single Cell At The Center Of The Embryo Sac.
After pollen is deposited on the stigma, it must germinate and grow through the style to reach the ovule. The meaning of double fertilization is fertilization characteristic of seed plants in which one sperm nucleus fuses with the egg nucleus to form an embryo and another fuses with polar nuclei to form endosperm. How does double fertilization occur in plants?
The Pollen Tube Cell And The Generative Cell.
The major steps of double fertilization consist successively of (i) the attraction of the pollen tube toward the embryo sac containing the female gametes, (ii) the release of the two male gametes into the degenerated synergid, (iii) the migration of the male gametes by unknown mechanisms to the two female gametes, (iv) gamete recognition and fusion, (v) the fusion of the parental. This is called a double fertilization. The process of fusion of one male gamete with the egg along with the union of the second male gamete with the two polar nuclei or the secondary nucleus is called double fertilisation.
