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 less general 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. | Real 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 |
