Practical purpose of taxonomy or classification is to:
1. facilitate the identification of unknown species
2. explain the origin of organisms
3. know the evolutionary history
4. identify medicinal plants
Biosystematics aims at:
1. | The classification of organisms based on broad morphological characters |
2. | Delimiting various taxa of organisms and establishing their relationships |
3. | The classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies |
4. | Identification and arrangement of organisms on the basis of cytological characteristics |
