Where does the egg and sperm fertilize?
A pregnancy starts with fertilization, when a woman’s egg joins with a man’s sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
What is fertilization class 12th?
Fertilization is defined as fusion of male and female gametes. This is the basis of sexual reproduction. Sexual reproduction is the production of offsprings by fusion of male and female sex cells known as gametes. The gametes are haploid that fuse and form the diploid zygote.
What happens when sperm capacitate?
Capacitation has two effects: destabilisation of the acrosomal sperm head membrane which allows it to penetrate the outer layer of the egg, and chemical changes in the tail that allow a greater mobility in the sperm. FPP comes into contact with the spermatozoa during ejaculation, as the sperm and seminal fluid mix.
How is an egg fertilized?
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus.
What happens to sperm after fertilization?
If a sperm cell does join up with your egg, the fertilized egg moves down the fallopian tube toward the uterus. It begins to divide into more and more cells, forming a ball as it grows. The ball of cells (called a blastocyst) gets to the uterus about 3–4 days after fertilization.

Where does the fertilization process take place in an animal?
The fertilization process in animals can occur either internally or externally, a difference which is largely determined by the method of birth. Animals which use viviparous and ovoviviparous reproduction (embryos develop within the animal’s body), and oviparous animals which lay hard shelled eggs, use internal fertilization.
What is the name of the second stage of fertilization?
This second fertilization forms a triploid cell, which subsequently swells and develops a fruiting body. The process of fertilization, which involves the cross-fertilization between gametes from two different individuals, male and female, is called allogamy.
