A haploid cell with have a haploid number, which is the number of chromosomes found within the nucleus that create one set. In humans, the haploid cells have 23 chromosomes, versus the 46 in the diploid cells. There is a difference between haploid and monoploid cells. Haploid cells have one complete set of chromosomes, whereas the term monoploid refers to the number of unique chromosomes in a biological cell. In diploid organisms, diploid cells contain the complete set of necessary chromosomes, while haploid have only half the number of chromosomes found in the nucleus.
