* Diploid: Diploid cells have two sets of chromosomes. This means they have twice the number of chromosomes found in a haploid cell.
* Haploid: Haploid cells have one set of chromosomes.
Example:
* Humans are diploid organisms. Our body cells have 46 chromosomes (23 pairs).
* Our sex cells (sperm and egg) are haploid. They have 23 chromosomes, one chromosome from each pair in our body cells.
In summary:
* Diploid: 2n (where 'n' is the number of chromosomes in a single set)
* Haploid: n
