When multiple sperm cells enter the ovum there are several possibilities that could happen depending on the later actions of the ovum. Essentially the ovum will divide into twins that could be identical, symetrical or neither.
The egg
The process of the union of a sperm cell and egg cell is fertilization. This union of two haploid cells makes a zygote, which changes to an embryo, and eventually makes a fetus.
It's not possible, because after one sperm cell reaches an egg, the egg cell slightly changes look to keep other sperm cells from reaching the same egg.
Male sex cells (gametes) are known as spermatozoa - or simply sperm.
IT takes about 2 hours for a healthy sperm to reach the fallopian tube of the uterus.
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.

The male produces sperm cells, which carry his genes. The sperm cell meets an egg cell from the female which carries her genes. The sperm cell penetrates the egg's outer layer. This is called "fertilizing" the egg. Normally, the outer layer of the fertilized cell thickens, so no more sperm cells can enter it. The fertilized egg then travels to the woman's uterus, where it attaches to the wall of the uterus and ultimately develops into a fetus.
The sperm cell is haploid (has half as many chromasomes as the diploid nerve cell)The sperm cell can contain more mutations (depending on the age of the man, this is the basis of anticipation)The sperm cell's chromasome has undergone recombination (I'm assuming you know what that is)
The egg cell has a chemical layer around it to stop more sperm cells coming in when a sperm cell comes in
In animals it would be called a sperm. In plants I assume the answer would be the pollen, however, the pollen is not necessarily one cell. Even if it is one cell it will have more than one nucleus (2 or 3).
More than one sperm will not enter the egg.
Cells enter mitosis to reproduce and grow more cells.
the stuff that comes out of men and helps make a baby and it gose in a grils flower a sperm is a cell that makes a grotty baby
The egg
fertilisation I think ... But so a bit more research yourself on it
