Haploid cells contain a single set of chromosomes.
Gametes are an example of haploid cells produced as a result of meiosis.
Examples of gametes are the male and female reproductive cells, the sperm and egg cell repectively.
The number of chromosomes in these gametes are 23, while diploid cells contain 46 chromosomes.
Organisms that have a hapolid life cycle include most fungi (with dikaryotic phase) , algae (without dikaryotic phase) and male ants and bees.
