Cells that contain two sets of chromosomes are called diploid cells.

Here's a breakdown:

* Diploid cells have two complete sets of chromosomes, one set inherited from each parent. This is the typical state for most somatic cells (body cells) in multicellular organisms.

* Haploid cells have only one set of chromosomes. Examples include gametes (sperm and egg cells).

So, to answer your question directly: Diploid cells contain two sets of chromosomes.
