 Aristotle's biology " 4. He watched the development of seeds and was able to some extent to distinguish be- tween dicotyledons and monocotyledons. " 5. He established a relationship between structure and habits, and approaches the con- ception of geographical distribution. "6. He saw the need for a general classifi- cation of plants and made some attempt at a system, though he failed to produce one which was in fact workable. " 7. He perceived a general relation be- tween structure and junction in plants, and thus laid the basis of scientific botany." ^^ [83]
