Animals, dogs and mammals represent
1. Taxa at different levels
2. Taxonomic hierarchy
3. Taxa at equivalent level
4. Categories at equivalent level
Study of diversity of organisms and evolutionary relationship amongst them on the basis of all possible characters is called as
1 Taxonomy
2 Systematics
3 Alpha-taxonomy
4 Phylogeny
First step of taxonomy is
1 Classification
2 Nomenclature
3 Identification
4 Characterisation
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
The term ‘systematics’ refers to
1. identification and study of organ systems
2. identification and preservation of plants and animals
3. diversity of kinds of organisms and their relationship
4. study of habitats of organisms and their classification
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 |
