WebA cell can be diploid and haploid at the same time. Let's exemplify this with organisms that perform gametic meiosis: Human beings have diploid somatic cells, with 46 chromosomes. When a somatic human cell perform meiosis, it produces haploid cells which are monoploid. Human gametes are haploid and monoploid. WebAn antheridium is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm ).
