Words that got left out of the word bank but are still important to know:

70 meiosis = form of cell division occurring only in specialized cells within the sex organs

71 gonads = sex organs

72 gametes = sex cells (egg/ovum or sperm)

73 zygote = fertilized cell (union of sperm & egg cells) containing 2 sets of chromosomes
