double fertilization

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.

What is double fertilization Why is it called so?

importance in angiosperm development

This is called double fertilization because the true fertilization (fusion of a sperm with an egg) is accompanied by another fusion process (that of a sperm with the polar nuclei) that resembles fertilization.

What is double fertilization with diagram?

The process of fusion of one male gamete with the egg along with the union of the second male gamete with the two polar nuclei or the secondary nucleus is called double fertilisation. Out of the two male gametes, one fuses with the egg to carry out generative fertilisation or syngamy.

What is double fertilization Class 12?

What is Double Fertilization? Double fertilization is a chief trait of flowering plants. In the phenomena, one female gamete unites with two male gametes. One of the male gametes fertilizes the egg resulting in the formation of a zygote and the other unites with 2 polar nuclei for the formation of an endosperm.

What is double fertilization and triple fertilization?

Double fertilization is the fusion of the embryo sac with two male gametes. It occurs in angiosperms. ... The fertilization of a sperm cell with the central cell is called triple fusion. Since the embryo sac is fertilized twice, the fertilization of gametes in angiosperms is called double fertilization.

What happens during double fertilization?

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.

What is double fertilization short?

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). ... Some plants may form polyploid nuclei.

What is double fertilization topper?

Double fertilization is a characteristic feature of flowering plants. In double fertilization, out of the two sperm nuclei, one sperm nucleus fuses with the egg nucleus to form an embryo. ... The other sperm nucleus fuses with polar nuclei to form endosperm. This process is called triple fusion.

What is human double fertilization?

Each is fertilized independently, and each becomes an embryo. With identical twins, one egg is fertilized by one sperm, and the embryo splits at some later stage to become two. Occasionally, two sperm are known to fertilize a single egg; this 'double fertilization' is thought to happen in about 1% of human conceptions.

What happens to ovule after fertilization?

After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
