One pollen grain has two male gametes. When pollen grain goes sticks to stigma ,a pollen tube is made which goes towards ovary. There one of the gamete fuses with egg cell to form zygote then to embryo. Other gamete fuses with the polar nuclei in the ovary to form endorsperm .
Fertilisation in which two time fertilisation occurs in single time

Okk bro
Double circlation is related with blood circlation and double fertilisation as per explained by khushi
Bhai double circulation aur double fertilisation alag hai
Its not double fertilization it double circulation
In plants-In angiosperm doble fertilization occurs. There will be 2 male germ cells. One male germ cell fusses with female germ cell to form zygote. Another male germ cell fuses with endosperm to form secondary nucleus.

there are two male gametes present so during fertilisation one of them fuses with female gamete to form zygote and other fuses with polar nuclei present on ovule . this is called double fertilisation

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).

Double fertilisation is the process occurring in pants
In angiospermic flower fertilization happen twice,generative nucleus 1st fertilize with egg cell 2nd with polar nucleus
The process of syngamy and triple fusion together is called double fertilization (occurs in plants)

When the pollen grain reaches to the stigma of carpel then it form a pollen tube which extent downward , through style it reaches ovary and then enters to ovule through micropileThis pollen tube then bust and one male gamete fused with egg to form zygote and other male gamete fused with two pollen nuclie to form triploid cell called endosperm ( this fussion is called triple fission ) and this phenomena is called double fertilisation…

When a female gamate is fertilise by two male gametes then this type of fertilisation is known as double fertilisation. Twins are the result of double fertilisation.
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, embryo sac) with two male gametes (sperm).The fertilization process characteristic of flowering plants, in which one sperm cell of a pollen grain fertilizes an egg cell while a second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm.It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower. The pollen grain then takes in moisture and begins to germinate, forming a pollen tube that extends down toward the ovary through the style. The tip of the pollen tube then enters the ovary and penetrates through the micropyle opening in the ovule. The pollen tube proceeds to release the two sperm in the megagametophyte.

Soon after pollination the pollen grains start germinating and form a pollen tube. The pollen tube grows within the style till it reaches the ovary.On reaching the ovary it enters the ovule through an opening called micropyle. In the meantime, two male gametes are formed in the pollen tube. One of the male gametes fuses with the egg, the process is called syngamy. The product formed is termed as zygote. The other male gamete fuses with the two polar nuclei, one from each end of embryo sac, to form endosperm nucleus. This process is called triple fusion. In this process three nuclei, two polar nuclei and one male gamete is involved, so it is called triple fusion. Thus, inside each embryo sac two fusions, i.e., syngamy and triple fusion take place. This mechanism of two fusions occurring in an embryonal sac is called double fertilisation. After fertilisation, the ovule develops into seed and the ovary develops into a fruit.
