Study Notes
Life Science & Environment
- Plants provide natural products for treating various illnesses
- Medicinal plants include Penicillium, Rauwolfia, Aloevera, Cinchona, and Belladonna
- Diseases treatable with antibiotics like Penicillin, Chloromycetin, and Streptomycin
- Space Biology (Exobiology) is a new field combining space research and biology
- Chlorella, a green algae useful in space, produces oxygen during photosynthesis
Taxonomy and Taxonomic Hierarchy
- 1.7 million species of living organisms are currently known
- Many additional species are yet to be discovered (~15,000 new species annually)
- Estimating the total number of species could reach 30 million species globally.
- Classifying organisms is crucial for studying and identifying them.
- Taxonomy is the branch of biology focusing on classification, nomenclature, and identification of organisms.
- "Taxonomy" derived from Latin words "taxis" (arrangement), and "nomos" (rules/laws).
- Early classification systems:
- Historical records (2500-650 BCE) included 740 plants and 250 animals
- Chāndogya Upaniṣad classified organisms into three groups (Jivaja, Andaja, Udbhija)
- Hippocrates and Aristotle also contributed to early biological classification
- Categorized organisms as plants and animals
- Aristotle further divided animals into four groups
