In sexual reproduction, an organism get half of it's genes from it mother and half from the father. Without the genes from both the egg and sperm, the genome of the new organism would be incomplete.
when the age of puberty , you will have that when the right time Blah! From the age of puberty onwards, males continue to produce sperm in the testes throughout their lives. Females, however, are born with all the eggs they will ever produce and are released generally once per monthly cycle. For the exact formation of each, you will need to grab a biochemistry textbook. But I bet it's not as exciting as liver functions!
In a grain of pollen,what is the function of the sperm cell that doesn't join with the egg cell?
Sex cells have 1/2 the number of chromosomes of a normal cell (23)
The gametes of a plant are found in the pollen grains (male) and the ovules (female). Pollen is normally transferred from the anthers of one plant to the stigma of another, either by animal agents or the wind. The pollen grows a tube down through the style and the gamete travels down to join with the female gamete. This is the actual fertilization. The fertilized ovule develops into the seed.
The male and female gametophytes join to form a zygote.
Otherwise , there would not be fertilisation! This is essential for reproduction.

Two zygotes will be formed after fertilization.
An egg cell and a sperm cell.
Each Egg and each Sperm contain only half of the genetic material to make a new animal (a baby). Thus if they do not join then the two parts of the genetic material can never come together.

Fertilization.
fertilization
fertilization occurs after the egg and sperm join together to make a zygote
to form a zygote !!
It's called, fertilization... I'm pretty sure its spelled correctly.
