Introduction to Unit 9 : Important Topics To Read
Unit 9 recollects the syllabus of our Board Exams, and now it’s been a quite long time to remember the Classifications, Taxonomy …etc .
Don’t Panic. The e-learning portal provides you the tips to memorize and recall the concepts easily.
Unit 9: Carrying an average weight age of 20 marks in the exam, this unit focuses on taxonomic units and the classification of plants, animals and microorganisms, the different diverse forms of life. The challenge is that there are a lot of scientific names, taxa, and terminologies to memorize, so preparation may be time-consuming and tedious.
Skipping this unit poses a problem too, as you may expect questions requiring knowledge of mixed facts from this unit and ecology or evolution as well.
Syllabus for Unit 9
9. DIVERSITY OF LIFE FORMS:
A. Principles & methods of taxonomy: Concepts of species and hierarchical taxa, biological nomenclature, classical & quantitative methods of taxonomy of plants, animals and microorganisms.
B. Levels of structural organization: Unicellular, colonial and multi-cellular forms. Levels of organization of tissues, organs & systems. Comparative anatomy, adaptive radiation, adaptive modifications.
C. Outline classification of plants, animals & microorganisms: Important criteria used for classification in each taxon. Classification of plants, animals and microorganisms. Evolutionary relationships among taxa.
D. Natural history of Indian subcontinent: Major habitat types of the subcontinent, geographic origins and migrations of species. Comman Indian mammals, birds. Seasonality and phenology of the subcontinent.
E. Organisms of health & agricultural importance: Common parasites and pathogens of humans, domestic animals and crops.
F. Organisms of conservation concern: Rare, endangered species. Conservation strategies.
Important Topics to be studied From CSIR NET Unit 9
- alpha-beta-gamma taxonomy
- Hierarchical taxa
- binomial nomenclature
- different protozoan and bacterial diseases
- common parasite and pathogens for different hosts
- questions are asked about the causative organisms with respective diseases
- the evolutionary relationships among taxa (graphical or phylogenetic tree, common ancestor based questions expected)
- rare and endangered species and their conversation strategies. This last topic is common with Ecology as well.
