In the phenomena, one female gamete unites with two male gametes. The germination of the pollen tube requires water, oxygen, and definite chemical signals.

During the process of triple fusion, endosperm development of three types are noticed, which are given below. Required fields are marked *, Double Fertilization Or Triple Fusion Are Common In. Which of the following is a post fertilisation event in flowering plants? If 6n female plant is crossed with a 4n male plant then the ploidy level of endosperm cell would be . It provides extra protection for the species –. Let us study about double fertilisation and triple fusion. He has published extensively on various aspects of the development of vascular plants, especially on zygotic and asexual embryogenesis in flowering plants.

Because there are two male gametes involved in the reproductive procedure, the development of the seed occurs with extra speed compared to other forms of reproduction. All rights reserved. The main advantage present in the double fertilization of angiosperms is energy conservation.

The kind of fertilization observed in most of the angiospermic plants where one male gamete (n) fertilizes female gamete (n) and the other male gamete fertilizes the definitive nucleus (2n) at a time is called double fertilization. Double fertilization definition 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 is an Ovary Turned into a Fruit after Fertilization? The main difference between triple fusion and double fertilization is that in double fertilization, the embryo sac and two sperm cells fuse, whereas the sperm nucleus and two polar nuclei fuse in the central cell of the embryo sac in the process of triple fusion. Some plants can even use this procedure as an additional food resource should growing conditions be less than complimentary when the new plant first emerges. An ovary contains at least one ovule. In double fertilization, an embryo is produced within the seed that will ultimately construct development. 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. This happens during double fertilization in a seed plant, and therefore gives origin to a triploid nucleus known as the Primary Endosperm Nucleus(PEN).

Double fertilization produces one diploid cell and one triploid cell. These three cells are haploid, which means they have one set of chromosomes, and is designated by n. In diploid (2n) cells, one set of chromosomes comes from the male parent and the other set comes from the female parent. Double Fertilization: Embryo and Endosperm Development in Flowering Plants. Double fertilization is a complex fertilization mechanism of flowering plants. No Kindle device required. View Answer. The fertilized ovule forms the seed, whereas the tissues of the ovary become the fruit, usually enveloping the seed.
