Haploid organisms such as fungi, yeast, and algae can have complex cell cycles, in which the choice between sexual or asexual reproduction is fluid, and often influenced by the environment. Some organisms, in addition to their usual haploid state, can also exist as diploid for a short time, allowing genetic recombination to occur.
The have twice the amount of chromosomes as in haploid cells. Haploid cells reproduce using meiosis, while diploid cells use mitosis. a haploid cell has half the amount of chromosomes of a diploid cell. human germ cells are haploids (the egg and sperm) they each contain 23 chromosomes.
