The cells that contain 46 chromosomes are called somatic cells. These are all the cells in your body except for sperm and egg cells (gametes).

Here's why:

* Humans are diploid organisms, meaning we have two sets of chromosomes, one from each parent.

* Each set has 23 chromosomes, for a total of 46 chromosomes in most cells.

* Gametes (sperm and egg cells) are haploid, meaning they only have one set of 23 chromosomes. This is so that when they combine during fertilization, the resulting zygote will have the correct number of chromosomes (46).

So, all your body cells, from your skin cells to your muscle cells, have 46 chromosomes!
