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 |
Which arrangement is in correct ascending order?
| 1. | Species < genus < order < family |
| 2. | Genus < species < family < order |
| 3. | Order < family < genus < species |
| 4. | Species < genus < family < order |
Which of the following taxonomic category is more common in characters as compared to the taxonomic category ‘Genus’?
| 1. | Species | 2. | Division |
| 3. | Class | 4. | Family |
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 |
Species are considered:
| 1. | basic units of classification |
| 2. | The lowest units of classification |
| 3. | The artificial concept of the human mind which cannot be defined in absolute terms |
| 4. | Real units of classification devised by taxonomists |
