The term used for the number of chromosomes found in a cell is ploidy.

Here's a breakdown:

* Ploidy refers to the number of sets of chromosomes in a cell.

* Haploid cells have one set of chromosomes (n).

* Diploid cells have two sets of chromosomes (2n).

* Polyploid cells have more than two sets of chromosomes.

For example, humans are diploid, meaning our cells have 23 pairs of chromosomes, for a total of 46 chromosomes.
