What is the difference between a cell that is diploid and one that is haploid?

A: Testes or ovaries of the male or female reproductive organs

B: Produced in the testes, then are stored in the epydidimis, then travel in the vas defferen, then are passed by the seminal vesicles, travel in the urethra and out the urethra opening.

C: A haploid is half of the cell (2), when the diploid is the whole. Like 23 is the haploid, 46 is the diploid.

D: So that every species is not the same, meaning that if a disaster would arise, the species would not all die off if a huge sickness came. (increased resiliency)
