From aardvark to zymogen granule, Barron's biology dictionary provides definitions and explanations of more than 6,000 biological terms. It'll set the love lights blazing in the eyes of any biology student, but it's also a fine library addition for the armchair biologist, the young science amateur, or any aging Saturday scientists. An essential reference for students struggling though science texts, Norah Rudin's dictionary also makes for interesting perusal fodder for them what enjoy browsing through aqueous humor, hyperplasia, mitochondrial cytopathies, northern blot, and spermatogenesis.
