Generally, a cactus has 22 chromosomes arranged as 11 pairs. Such a cactus is called 'diploid', from the Greek 'diploos' and 'eidos' for 'double' and 'form', respectively. In the way of comparison, humans tend to have 46 chromosomes arranged as 23 pairs. But some cactus plants have more than two sets of chromosomes. For example, it's possible for a cactus to have 44 or even 66 chromosomes. Such a cactus is called 'polyploid', from the Greek 'polu' and 'ploos' for 'many' and 'fold', respectively.
