* Cells with pairs of chromosomes: These are called diploid cells. Diploid cells have two sets of chromosomes, one set inherited from each parent. This is the typical state for most of the cells in your body.
* Cells with no chromosomes: This is not possible for a living cell. Chromosomes carry the essential genetic information necessary for a cell to function and survive. Even bacteria, which have a single circular chromosome, cannot exist without it.
A few additional points:
* Haploid cells: Some specialized cells, like sperm and egg cells (gametes), have only one set of chromosomes. These are called haploid cells. When a sperm and egg combine, they form a diploid zygote.
* Chromosomal abnormalities: While it's not possible for a cell to have zero chromosomes, there are conditions where cells can have an abnormal number of chromosomes, like Down syndrome (trisomy 21).
