How does double fertilization occur in flowering plants?
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 in plants explain?
Definition of double fertilization : fertilization characteristic of seed plants in which one sperm nucleus fuses with the egg nucleus to form an embryo and another fuses with polar nuclei to form endosperm.
In which of the following plants double fertilization occurs?
flowering plants
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called as the embryo sac) with two male gametes (sperm).
What is double fertilization short answer?
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 quizlet?
-Double fertilization is a process in angiosperm plants in which two sperm are required to fertilize the contents of the embryo sac. -The pollen grain which is the male gametophyte lands on the stigma and germinates.
What is double fertilization why it is called so?
One sperm nucleus unites with the egg to form the diploid zygote, from which the embryo develops. The other sperm unites with the two polar nuclei located in a single cell at the center of the embryo sac. Since the fusion between sperms and female gamete occurs twice, it is called double fertilisation.
What is double fertilization in plants Brainly?
Answer: Double fertilization is a complex fertilization mechanism of flowering plants. This process involves joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.

How does double fertilization occur in flowering plants quizlet?
In double fertilization, one sperm reaches the egg and fertilizes it. This produces a diploid zygote that will grow into the plant embryo. A second sperm fuses with the endosperm nuclei in the embryo sac and produces the triploid endosperm. This will nourish the developing seedling.
What is produced when double fertilization occurs in angiosperms quizlet?
In angiosperms, they have double fertilization to produce the triploid endosperm and the diploid zygote.
What is meant by double fertilization quizlet?
What is double fertilization Class 10 CBSE?
Double fertilization : It occurs when one male nucleus fertilizes (fuses) with egg cell to form zygote cell and other male nucleus fuses (fertilizes) with two polar nuclei to cause triple fusion.
What is double fertilization class 10th by Brainly?
What is double fertilization in plants quizlet?
What are the results of double fertilization quizlet?
Double fertilization is where one sperm fertilizes the egg (results in 2N zygote) and one sperm fertilizes both polar nuclei (results in 3N endosperm= food for zygote).
What is double fertilization Class 7?
Double fertilisation: It is the process of fusion of one male gamete with the egg nucleus and another male gamete with the polar nuclei or secondary nucleus is called double fertilisation.
What is the double fertilization Brainly?
In which plants life cycle does double fertilization occur quizlet?
What are the steps of double fertilization?
What are the steps of 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 meant by double fertilization?
Double fertilization is the combination of one male and one female spore, which form a zygote, whereas triple fusion is the combination of spore with the fertilized egg. In double fertilization, only one spore and one egg are combined; on the other hand, in triple fusion, there is the combination of one fertilized zygote with the spore.
What is the process of double fertilization?
In double fertilization,two products are formed
What are the four stages of fertilization?
Sperm is attracted to and contacts the jelly layer/zona pellucida.
