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. |
