Here's why:
* Haploid cells have half the number of chromosomes compared to diploid cells. They are usually involved in sexual reproduction.
* Diploid cells have two sets of chromosomes, one from each parent. They are the typical cells found in most organisms.
Examples of haploid cells include:
* Gametes: Sperm and egg cells in animals, and pollen and ovules in plants.
* Spores: In some plants and fungi.
