What is double fertilization and diagram?
The process in which fusion of male gamete with eggs and another male gamete with the nucleus takes place in an embryo sac is termed as double fertilization. In the flowering plants after entering one of the synergids the Pollen tube releases the two male gametes into the cytoplasm of synergids.
What is double fertilisation explain with diagram?
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 explain in detail with diagram?
The process in which fusion of male gamete with eggs and another male gamete with the nucleus takes place in an embryo sac is termed as double fertilization. In the flowering plants after entering one of the synergids the Pollen tube releases the two male gametes into the cytoplasm of synergids.
What is double fertilization class 10 with diagram?

What is double fertilization with diagram class 12?
The process in which fusion of male gamete with eggs and another male gamete with the nucleus takes place in an embryo sac is termed as double fertilization. In the flowering plants after entering one of the synergids the Pollen tube releases the two male gametes into the cytoplasm of synergids.
What is double fertilisation explain?
double fertilization, in flowering plant reproduction, the fusion of the egg and sperm and the simultaneous fusion of a second sperm and two polar nuclei that ultimately results in the formation of the endosperm (the food-storage tissue) of the seed.Dec 12, 2022
What is double fertilization write its importance class 12?
It involves the fusion of one male gamete with the egg to form a zygote (syngamy) and another male gamete with two polar nuclei to form endosperm (triple fusion). Complete answer: Two significance of double fertilization are: -The most important significance of double fertilization is energy conservation.
What is fertilization explain with diagram?
Diagram: 1 Mark. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus. This results in the formation of a fertilized egg or zygote.
What is double fertilization in angiosperms explain with suitable diagram?
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).
What is double fertilization in angiosperms explain it with suitable diagram?
Double fertilization is the characteristic of angiosperms. In this process, one male gamete fuses with the egg to form a zygote, which is known as syngamy. The other male gamete fuses with the two polar nuclei in the central cell to produce a triploid primary endosperm nucleus or PEN.
What is double Fertilisation explain?
Out of the two male gametes one gamete fuses with the egg nucleus while the other fuses with the polar nuclei to form PEN(Primary Endospermic Nucleus). Since fusion occurs twice the process is known as double fertilization.
