Exppain the process of double fertilization and its significance
Answers
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm). ... The pollen tube proceeds to release the two sperm in the megagametophyte.
significance1: A pollen tube releases two sperm cells into an unfertilized ovule. 2: Double fertilization occurs when one sperm cell fuses with the egg to produce a zygote, and the other sperm cell fuses with the two polar nuclei to make the endosperm. 3: After double fertilization, a seed and fruit develop.
The process of fusion of male gamete with the female gamete to form a diploid zygote (2n) is calledfertilization. The fusion of one male gamete with the egg and another male gamete with the secondary nucleus is called double fertilization.
The Significance of double fertilization of angiosperms is energy conservation. The endosperm formed by fusion of the two polar nuclei and a sperm only begins to develop and store nutrients after it has been fertilized by a sperm cell.
