fertilization
Zygote is formed by the unification of an ovum and a sperm.Sperm provides the nucleus whereas the oven provides the cytoplasm of the zygote.Union of a sperm and a ovum is called fertilization and zygote formed in this way is diploid in nature.
The Fertilized Ovum gives rise to all the cells pf the human body by a series of cell division.
The plasma membrane of the ovum controls what goes in and out of the ovum. The Zona Pellucida also known as the jelly coat is responsible for the binding of the sperm during fertilization. The outermost layer called the corona radiata provides the ovum with essential proteins and protects the ovum as it travels down through the fallopian tubes.
Sperm+ ovum= Zygote
An ovum or egg is what is called a 'gamete'. A gamete is a cell produced for sexual purposes by a special process of cell division called meiosis in which the number of chromosomes per cell is cut in half. Thus the ovum has only 1/2 the amount of DNA needed to make new baby.In male's meiosis produces sperm and the joining together of the male's sperm and the female's ovum - fertilization - makes the new 'embryo' which now has the correct amount of DNA to make the baby.
Fertilization occurs when a sperm cell and an ovum fuse, resulting in a fertilized egg.
The uniting of an egg and sperm cell is called unification
Fertilization
that is the egg that get's fused with the sperm for fertilization
fertilization
This usually occurs in the Fallopian tubes.
