What is double fertilization and triple fusion Class 10?
One male gamete fuses with the female gamete and the other fuses with the secondary nucleus. As two male gametes take part and fertilization and fertilization takes place twice, this process is called double fertilization. Since three gametes are involved it is called triple fusion.
What is double fertilization 10th?
Double fertilization is a complex process where out of two sperm cells, one fuses with the egg cell and the other fuses with two polar nuclei which result in a diploid (2n) zygote and a triploid (3n) primary endosperm nucleus (PEN) respectively.
What is the fertilization Class 10?
Fertilization is the process of fusion of male and female sex cells(gametes). It is the process which occurs after pollination.
What is double fertilization class 10 brainly?
Answer: Double fertilization is a complex fertilization mechanism of flowering plants. This process involves joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.Feb 27, 2020
What is triple fertilization class 10?
It is a process involved in the sexual reproduction of angiosperms. Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation. The fusion process occurs in the embryo sac of the angiosperms.
What is fertilization science class 10?
Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel. The complete series of this process takes place in the zygote to develop into a seed.

What is double fertilization and double fusion?
double fertilization, in flowering plant reproduction, the fusion of the egg and sperm and the simultaneous fusion of a second sperm and two polar nuclei that ultimately results in the formation of the endosperm (the food-storage tissue) of the seed.Dec 12, 2022
What is double fusion?
It is a complex process in which out of the two sperm cells, one combines with the egg cell, and the other combines with the two polar nuclei resulting in the formation of a diploid zygote and a triploid primary endosperm nucleus.
What is the fusion of double fertilization?
Double fertilization is fusion of one male gamete with egg resulting in the formation of zygote and other male gamete with secondary nucleus forming PEN.
