What is called syngamy?
Syngamy (frequently labeled by “Y!”), is the fusion of two cells, resulting in a cell that has twice as many chromosomes. The two cells which are fused together are called gametes, and the resulting cell is a zygote. The goal of syngamy is the renovation of genetic material.
What is meant by triple fusion?
: the fusion involving two polar nuclei and a sperm nucleus that occurs in double fertilization in a seed plant and results in the formation of the endosperm.
What is syngamy class 10th?
Syngamy is the fusion of gametes to initiate the development of a new individual organism. The cycle of fertilisation and development of new individuals is called sexual reproduction.
What is triple fusion class 10th?
It is a process involved in the sexual reproduction of angiosperms. 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.
What’s the difference between triple fusion and syngamy?
Triple fusion can be defined as the fusion of sperm nuclei with two polar nuclei in the embryo sac of flowering plants. It results in triploid cells which develop into endosperm of the seed to nourish the embryo. This is the difference between syngamy and triple fusion.
How is triple fusion different from double fertilization?
The main difference between triple fusion and double fertilization is that in double fertilization, the embryo sac and two sperm cells fuse, whereas the sperm nucleus and two polar nuclei fuse in the central cell of the embryo sac in the process of triple fusion.
Which is the end result of triple fusion?
The end result, outcome of the process of triple fusion is the formation of the endosperm. During the process of triple fusion, endosperm development of three types are noticed, which are as follows:
When does triple fusion occur in an angiosperm?
What is Triple Fusion. Triple fusion is the fertilization of the two polar nuclei in the embryo sac. It occurs during the double fertilization of angiosperms. While one sperm cell fertilizes the egg cell in the embryo sac, the other sperm cell fertilizes the two polar nuclei found in the central cell.
