The system of classification of plants given by Carolus Linnaeus was:
1. an artificial system based mainly on the androecium structure.
2. a natural system based on large number of natural affinities between flowering plants.
3. was a phylogenetic system based on evolutionary relationships.
4. was a chemotaxonomic system based on structure of homologous proteins.

Which statement accurately describes the difference between artificial and natural systems of classification?
1. Artificial systems utilize genetic similarities, whereas natural systems use morphological characteristics.
2. Artificial systems classify organisms based on a few characteristics, while natural systems consider a large number of characteristics.
3. Artificial systems classify organisms based on evolutionary relationships, while natural systems focus on ecological roles.
4. Artificial systems are based on observable characteristics, while natural systems are more theoretical.
