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." ^^
