Yes, that is the basic idea. Only one sperm cell enters the egg; there are rapid chemical reactions that take place preventing other sperm cells from entering.

Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.

What are 2 kinds of sex cells that a gametophyte produces?

Which cells have only 23 unpaired chromosomes?
The only place you would be able to find a cell with 23 chromosomes would be in the sex cells (sperm cells of egg cells). There are 46 chromosomes in the human body. This is because when a sperm cell fertilises the egg cell, both with 23 single chromosomes, they join to make 46.
Which is larger the egg cell or the sperm cell?
