Only one sperm is required to fertilize an egg. One is both necessary and sufficient in order for an egg to be fertilized. But in order to be confident that one will make it, you need a certain minimum sperm count.

When an egg and a sperm join during fertilization they form the first cell of a new organism and this cell divides into many cells to form what?
to form a zygote !!
How many sperm cell and egg cell unite during fertilization?
Generally, one sperm cell and one egg cell unite for each offpring that is created (some cases, such as monozygotic/idential twins, are different). This means that if a human has one baby, it was one sperm and one egg. Or if a dog has 5 puppies, it was 5 egg cells and 5 sperm cells that united.
Why many sperm cell's needed to fertilize an egg cell?
Because out of a normal ejaculation of 200 million sperms, 90% are deformed which is normal. The actually fertilize an egg it only takes one.
During spermatogenesis a cell with 2n chromosomes divides to form four sperm cells. How many chromosomes are in each sperm cell?
8n
If a sex cell has eight chromosomes how many chromosomes will there be after fertilization?
in a normal human cell there are 46 chromosomes but sex cells only have half these (23) because when the female sex cell and the male sex cell come together and fertilise they add up to 46 (making a human cell which will multiply into a baby human) In your questions state you are only using 8 so a normal cell would have double that (16) to make a baby of that species of animal or plant ect.
How many chromosomes does a sperm cell have prior to fertilization?
23
How many chromosomes does a human sperm or egg cell contain?
The human egg or sperm cell is haploid and contains 23 chromosomes. After fertilization (egg and sperm fusion), the zygote will have 46 chromosomes (23 pairs).
When an egg and a sperm join during fertilization they form the first cell of a new organism and this cell divides into many cells to form what?
to form a zygote !!
How many sperm cells can enter an egg cell?
Only one sperm fertilises an egg in normal cases, abnormally there are chances of fertilization by 2 or more sperm cells but such a zygote usually does not survive.
What contains chemicals to break through things a egg cell or a sperm cell?
A sperm cell contains chemicals to break through things. This is because on the sperm's way to the egg (fertilization) it has to get past many other things and needs a specially strengthened head to break through things.
How many sperm cells are necessary to chemically break down the egg cell wall?
Multiple sperm cells are involved in the process of fertilization, but only one sperm cell is needed to penetrate and fertilize the egg cell. Once the sperm cell penetrates the egg, it releases enzymes that break down the egg cell wall, allowing the genetic material of the sperm to enter the egg.
Why so many sperms are needed for fertilization to occur?
Actually, it only takes one sperm to fertilize the egg, but the problem is the journey to the egg. The male ejaculates so many sperm because most of them die on the way there, the lucky one that gets there cause the fertilization.
How many sperm cell and egg cell unite during fertilization?
Generally, one sperm cell and one egg cell unite for each offpring that is created (some cases, such as monozygotic/idential twins, are different). This means that if a human has one baby, it was one sperm and one egg. Or if a dog has 5 puppies, it was 5 egg cells and 5 sperm cells that united.
How many spermcells is needed by the eggcell?
An egg cell only needs one sperm cell to be fertilized. Human male ejaculate can contain 200 000 000 sperm.
Why is necessary to release so many sperm at a time?
to ensure the fertilization of the egg with the mostcompatible sperm
What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
How many sperm cell are there in one person?
A sperm is a single cell, so there is one cell per sperm.
