The joining of an egg and a spermatazoan (sperm) is called fertilization.
the egg is larger than the sperm cell
sperm fertalizes the egg cells.
The change in the egg's covering is due to a process called the zona reaction, which is triggered by the entry of the sperm into the egg. This reaction helps prevent other sperm from entering the egg, ensuring that only one sperm fertilizes the egg.
A sperm or egg alone can not develop into a new individual. Only an egg fertilized by a sperm does.
When a sperm comes in contact with an egg, the sperm releases enzymes to help it penetrate the egg's outer layer. Once a sperm successfully penetrates the egg, the outer layer of the egg changes to prevent other sperm from entering. This triggers the egg to start dividing and developing into an embryo.
