Cos right, i have the biggest japsi in the whole wide world.
There can be only one.
A sperm or egg alone can not develop into a new individual. Only an egg fertilized by a sperm does.
Egg cells are the biggest: you could only fit one on the head of a pin. But I'm not sure if a sperm cell is bigger than a red blood cell or vice versa.
A sperm and an egg.
the egg is larger than the sperm cell
When a fertile sperm reaches near a mature unfertilized egg, the capability of sperm to pears through the egg cell wall and discharge its nucleus makes it possible to fertilize the egg. This union of male and female gametes to form zygote is called fertilization.
Many sperm cells are needed to fertilize an egg cell because only one sperm cell can successfully penetrate the egg cell's protective layer and fuse with its nucleus to form a zygote. Competition among the sperm cells ensures that the strongest and healthiest sperm cell is most likely to successfully fertilize the egg.
The uniting is known as fertilisation of the egg by the sperm.
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.
Only one sperm cell is required to successfully fertilize an egg.
because when the sperm and egg meet they make one hole nucleolus. the sperm and egg have half a nucleolus and they are the only cell in the world to have only half a nucleolus.
So that the sperm can break through to fertalise the egg.Because it enters to egg cell through its head only. The enzymes present at the top of its head facilitate the penetration of sperm in the egg cell.
