Detailed explanation-1: -Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells.

Detailed explanation-2: -Cells containing two sets of chromosomes are called diploid. If the reproductive cycle is to continue, the diploid cell must somehow reduce its number of chromosome sets before fertilization can occur again, or there will be a continual doubling in the number of chromosome sets in every generation.

Detailed explanation-3: -Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells.
