Why triple fusion is called so?

It is called triple fusion due to the presence of 3 nuclei one from the sperm nuclei and two nuclei of polar nuclei. The fusion involves the two polar nuclei and a sperm nucleus that occurs in double fertilization leads to formation of endosperm. It means the presence of 3 nuclei (3n).

What is a triple fusion product?

Since there are three haploid nuclei, the process is known as triple fusion. The product of the triple fusion process is the formation of the endosperm. Endosperm tissue is present inside the seeds of the flowering plants which is then used in the fertilization. It provides essential nutrients to the in form of starch.

What is double and triple fusion?

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 triple fusion and where?

Triple fusion is fusion which involves the fusion of two polar nuclei and a sperm nucleus which occurs in double fertilisation in a seed plant and it further results in the formation of endosperm. This process occurs in the embryo sac of the angiosperms. The end result of this process is the formation of endosperm.

Where do male gametes take place?

Male gametes are contained within pollen grains, which are released from the anthers at anthesis.

What is Triple Fusion short note?

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. One of the two male gametes fuses with the nucleus of the egg cell to produce the zygote, this process is referred to as syngamy.

Is zygote product of Triple fusion?

The fertilization of one of the male gametes with the egg nucleus results in the formation of the zygote. In triple fusion, nuclei of both the male gametes are released in the embryo sac. One of these nuclei fuses with the egg nucleus resulting in the formation of a diploid zygote.

What is triple fusion Byjus?

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. Since the process involves the combining or fusing of three haploid nuclei, it is referred to as triple fusion.

What is triploid fusion?

A primary endosperm nucleus, triploid in nature is formed when the other male gamete combines with the two polar nuclei that are located in the central cell. Since the process involves the combining or fusing of three haploid nuclei, it is referred to as triple fusion.

Is triple fusion present in gymnosperms?

– Double fertilization and triple fusion are the key features of angiosperms and are completely absent in other groups of plants such as bryophytes, Pteridophytes and gymnosperms.

What is Double fusion?

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.

What is triple fusion and name the nuclei involved in triple fusion?

Fusion of male gamete with diploid secondary nucleus/central cell to form triploid primary endosperm nucleus is called as triple fusion as it involves three nuceli. It takes place in embryo sac during double fertilization. Two polar nuclei and male gamete are involved in it.
