Here's why:
* Chromosomes: Chromosomes carry genetic information. In most organisms, chromosomes come in pairs, one from each parent.
* Diploid: A cell with two sets of chromosomes (one from each parent) is called diploid.
* Haploid: A cell with only one set of chromosomes is called haploid.
Examples of Haploid Cells:
* Gametes: Sex cells like sperm and egg cells are haploid. They have half the number of chromosomes found in a normal body cell (somatic cell). This allows for the fusion of two gametes to form a diploid zygote with a complete set of chromosomes.
* Spores: In some organisms like plants and fungi, spores are haploid cells that can develop into new individuals.
Key takeaway: A haploid cell contains only one chromosome from each pair, while a diploid cell contains two chromosomes from each pair.
