What is double fertilization example?
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).
What is called double fertilization?
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 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 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 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 and triple fertilization 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 answer?
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).
What is double fertilization Class 7?
Out of the two male gametes one gamete fuses with the egg nucleus while the other fuses with the polar nuclei to form PEN(Primary Endospermic Nucleus). Since fusion occurs twice the process is known as double fertilization.
What is single fertilization and double fertilization?
The process of fusion of male gamete with the female gamete to form the diploid zygote (2n) is known as fertilisation. The fusion of one male gamete with egg and that of another male gamete with a secondary nucleus is called double fertilisation.
What do you mean by double fertilization Class 12?
By definition, double fertilization is a complex fertilization method where out of two sperm cells, one fuse with the egg cell and other fuses with two polar nuclei which results in diploid (2n) zygote and triploid (3n) primary endosperm nucleus (PEN) respectively.
What is double fertilization in class 12?
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.
