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.
Haploids contain only half as many chromosomes as compared to a diploid and hence they will contain only 8 chromosomes each.
Male and female gametes are the sex cells and are also known as sperm cells and daughter cells. Each of these gametes are haploids and they add up to a full set of chromosomes when they interact with one another (sperm cell with a daughter cell).
Hope this helps.
If the number of chromosome present in the diploid cell is 16, then the number of chromosome present in the haploid cell would be half the number of chromosome present in the diploid cell. This means that the number of chromosomes in the haploid cell would be 8. Male and female gametes are reproductive cells which are involved in the process of fertilization. Male and female gametes are produced by a type of cell division known as meiosis. The importance of meiosis is that the diploid number of chromosomes is reduced to the haploid number in the gametes. It also helps in maintaining a constant diploid number of chromosomes for a species.
