The sex cell for a woman is called the ovum(egg) and the cell for a man is called the sperm. Each sex cell contains half a strand of DNA(one chromozome). The two chromozomes combine to make a full set of DNA. XXchromozomes=girl. XYchromozomes=boy. The sperm's chromozome determines what gender the baby will be because females only have X and males have both X and Y.

Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.

Unlike asexual reproduction, two different cells are needed, that are haploid cells, for sexual reproduction. These haploid cells are gametes, and allow half of the maternal cell and half of the paternal cell to combine and produce a unique offspring. This combination also allows crossing over to occur and produce even more of a variation from the parents.
TO PRODUCE SEX CELLS involved in the production of offspring
Yes.
So they can produce healthy offspring.
Each will contribute the diploid number 23 so the resulting zygote will ahve the full 46 necessary chromosomes.This assumes you are discussing humans.
Sexual reproduction is the production of an offspring that results when the genetic materials from two different cells combine.
