Plant anatomy
It was in the late 1600s that plant anatomy became refined into a modern science. Italian doctor and microscopist, Marcello Malpighi, was one of the two founders of plant anatomy. In 1671 he published his "Anatomia Plantarum", the first major advance in plant physiogamy since Aristotle. The other founder was the British doctor Nehemiah Grew. He published "An Idea of a Philosophical History of Plants" in 1672 and "The Anatomy of Plants" in 1682. Grew is credited with the recognition of plant cells, although he called them 'vesicles' and 'bladders'. He correctly identified and described the sexual organs of plants (flowers) and their parts.
History of Animals
Walter Pagel comments that Aristotle "perceptibly influenced" the founders of modern zoology, the Swiss Conrad Gessner with his 1551–1558 "Historiae animalium", the Italian Ulisse Aldrovandi (1522–1605), the French Guillaume Rondelet (1507–1566), and the Dutch Volcher Coiter (1534–1576), while his methods of looking at time series and making use of comparative anatomy assisted the Englishman William Harvey in his 1651 work on embryology.
