As many somatic cells present in humans.
In humans, all the cells except for the sex cells are diploid cells. Diploid cells contain two sets of chromosomes, one set obtained from each biological parent. On the other hand, sex cells (gametes – eggs and sperm cells) are haploid cells containing only a set of chromosomes. Examples of diploid cells in humans are nerve cells, muscle cells, bone cells, skin cells, etc.
This was a brief on Diploid cells covering its definition, examples, some of its features, chromosome number in different species, in humans, haploid cells and differences between haploid and diploid cells.
