How many chomosomes in your body?

In a normal Human body cell (not a gamete) there are 46 chromosomes. This is not the same number of chromosomes in our bodies, only in one cell, and there are trillions of cells in the human body. In a gamete (a sperm cell or egg cell) there are 23 chromosomes. When the sperm and egg cell nuclei fuse in fertilisation, a diploid cell of 46 chromosomes is produced.

What is the difference between a body cell and a sex cell in terms of number of chromosomes?

Human cells have 46 chromosomes (call that 2n, or 2 times n). Now then, if an egg cell + sperm cell = fertilized egg (which becomes a human), how many chromosomes do each have? An egg cell must have 23 chromosomes, and a sperm cell must have 23 chromosomes, because 23 + 23 = 46. When the egg (23) and sperm (23) combine to form a fertilized egg, this egg will now have 46 chromosomes. So human sex cells have n, or 23 chromosomes. If you mean to distinguish somatic chromosomes from sex chromosomes, then you have 22 pairs of somatic chromosomes plus one pair of sex chromosomes, for a total of 46 chromosomes.

How many chromosomes does a gamete have compared to a somatic cell?

I will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.

How many chromosomes are in an human egg cell?

Human egg cells contain one set of 23 chromosomes. Because they contain half of the 46 chromosomes contained in body cells (2 sets of 23), the egg cells are said to be haploid.
