Final answer:
A human haploid cell is a cell that contains only one set of chromosomes, such as a sperm cell with 23 chromosomes.
Step-by-step explanation:
A human haploid cell is a cell that contains only one set of chromosomes, instead of the usual two sets found in most cells. One example of a haploid cell in humans is a sperm cell. Sperm cells are produced in the testes and contain half the number of chromosomes (23 chromosomes) compared to other cells in the body, which have 46 chromosomes. When a sperm cell fertilizes an egg cell, which is also haploid, they form a diploid zygote with a complete set of 46 chromosomes.
