Your question: Which part of the following is formed when second male gamete units with two polar nuclei?

Which part of the following is formed when second male gamete unites with 2 polar nuclei?

Second male gamete joins with two polar cores to shape Endosperm.

Which part of the following is formed when second male gamete unites with two polar nuclei in flowers a zygote B embryo C embryo sac D endosperm?

The second male gamete fuses with 2 polar nuclei or secondary nucleus to form triploid primary endosperm nucleus and this is called triple fusion. This primary endosperm nucleus (3n) ultimately develops into a nutritive tissue for developing embryo called endosperm.

What does the second male gamete forms after pairing with two polar nuclei?

The second male gamete fuses with 2 polar nuclei or secondary nucleus to form triploid primary endosperm nucleus and this is called triple fusion. This primary endosperm nucleus (3n) ultimately develops into a nutritive tissue for developing embryo called endosperm.

What is the process of union of male gamete with egg called?

Complete answer:When a male gamete, which in the case of humans is a sperm cell, fuses with a female egg cell, ovum in case of humans, it leads to the formation of a zygote, and this process is called fertilization. … Fertilisation– It is the union of haploid male and female gamete which leads to the formation of zygote.

What are the two nuclei at the end of the pollen tube called?

The two nuclei at the end of a pollen tube are called Tube nucleus and a generative nucleus.

Which polar nuclei fuse to form the endosperm?

One sperm nucleus fertilizes the egg cell, forming a zygote, while the other sperm nucleus usually fuses with the binucleate central cell, forming a primary endosperm cell (its nucleus is often called the triple fusion nucleus). That cell created in the process of double fertilization develops into the endosperm.

What is formed during the double fertilization process to help the sperm reach the egg in the ovary?

Double fertilization involves two sperm cells; one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.

When a male gamete fuses with two polar nuclei it forms a cell?

The first male nucleus fuses with the egg cell to form the zygote; the second male nucleus fuses with the two polar nuclei to form a triploid nucleus that develops into the endosperm.

What is formed when the second male gamete fuses with another cell in the ovule and it provides nourishment to the embryo?

The Endosperm Coenocyte. During the double fertilization process in angiosperms, one of the two male gametes carried by the pollen tube fuses with the egg cell nucleus to form the diploid zygote, and the other with the diploid central cell nucleus to form the endosperm.

What happens to the other male gamete?

Summary. In flowering plants, two male gametes from a single pollen grain fuse with two female gametes, the egg and central cells, to form the embryo and endosperm, respectively.
