## Step 1<br />The diploid number of chromosomes in an organism is the total number of chromosomes that it has in its body cells. This number is typically represented as 2n, where n is the haploid number of chromosomes. For tomatoes, the diploid number is 24, which means that each body cell contains 24 chromosomes.<br /><br />## Step 2<br />The haploid number of chromosomes is the number of chromosomes in a gamete (sex cell) of an organism. This number is typically represented as n. For tomatoes, the haploid number is 12, which means that each gamete contains 12 chromosomes.<br /><br />## Step 3<br />The number of chromosomes in each body cell of an organism can vary. However, humans typically have 46 chromosomes in each of their body cells.<br /><br />## Step 4<br />In humans, the only cells that contain 23 chromosomes are the gametes, which are the sex cells (sperm and egg). This is because these cells are haploid, meaning they contain half the number of chromosomes as a normal body cell.
