The term diploid refers to the number of chromosomes found
in the nucleus of a regular body cell (liver cell, nerve
cell, muscle cell, skin cell, etc.). Regular body cells are sometimes called diploid
cells. The prefix 'di' means 2, so a diploid cell contains 2 sets of chromosomes in
each, one set from the mother and one set from the father. The term haploid refers to
the number of chromosomes found in the nucleus of a sex
cell, which is a sperm cell or egg cell. Haploid cells contain half the
number of chromosomes as the body cells (haploid=half). If a
diploid cell contained 16 chromosomes, 8 from the mother
and 8 from the father, then the haploid cell, or sex cell,
would contain half as much or 8 chromosomes.
The term
gamete is the scientific name for the sex cell. The male gamete is the sperm cell and
the female gamete is the egg cell.
