Biosystematics aims at
1. the classification of organisms based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies
2. identification and arrangement of organism on the basis of their cytological characteristics
3. the classification of organisms based on broad morphological characters
4. delimiting various taxa of organisms and establishing their relationships
1. | Cladistics | 2. | Systematics |
3. | Taxonomy | 4. | Identification |
Species are considered as
1. artificial concept of human mind which cannot be defined in absolute terms
2. real units of classification devised by taxonomists
3. real basic units of classification
4. the lowest units of classification
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

3. look similar and possess identical secondary metabolites
4. have same number of chromosomes
