What is plant fertilization Slideshare?
Fertilization is the process of fusion of the female gamete, the ovum or egg and the male gamete produced in the pollen tube by the pollen grain. … The male gametes of the flower are transferred on to the female reproductive organs through pollinators.
Why is fertilisation in plants known as double Fertilisation?
Fertilisation in flowering plants is referred to as double fertilisation because both the male gametes of the same microspore take part in fusion. One fuses with the egg to form the diploid zygote, and the other fuses with the two polar nuclei (or secondary nuclei) to form the triploid primary endosperm nucleus.
Why is fertilization called double fertilization in plants?
One male gamete fuses with the egg cell to form the zygote, whereas the second male gamete fuses with two polar nuclei in the embryo sac to form an endosperm. Since, in flowering plants, the process of fertilization occurs twice in the same embryo sac, by two male gametes, it is called as double fertilization.
What is fertilization give example?
Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either inside (internal fertilization) or outside (external fertilization) the body of the female. Humans provide an example of the former whereas seahorse reproduction is an example of the latter.
How is fertilization in flowering plants different from fertilization in other plant groups?
How is fertilization in flowering plants different from fertilization in other plant groups? One sperm nucleus fuses with the egg to form a diploid zygote, whereas the other sperm nucleus fuses with two polar nuclei to form a cell that develops into endosperm. … In angiosperms, each pollen grain produces two sperm.
Can a girl get pregnant by another girl?
The short answer to this question is no, not through sexual intercourse. Two cisgender women (meaning assigned female at birth) in a relationship cannot become pregnant without some form of assisted reproductive technology (ART).
