| Cue/Question | Notes |
|---|---|
| What defines life? | Metabolism = sum of all anabolic (constructive) + catabolic (destructive) chemical reactions. Only property: (1) present in ALL living organisms; (2) absent in ALL non-living entities. |
| Why not growth? | Crystals grow by accumulation (non-living). Dead organisms do not grow. Growth is not exclusive to life. |
| Why not reproduction? | Mules (sterile hybrid), worker bees (sterile females), infertile humans — all are alive but cannot reproduce. NOT universal. |
| Who coined "taxonomy"? | A.P. de Candolle — NOT Linnaeus. |
| Who established binomial nomenclature? | Carolus Linnaeus — in "Systema Naturae." |
| Taxonomic hierarchy? | Kingdom → Phylum/Division → Class → Order → Family → Genus → Species. Mnemonic: "King Philip Came Over For Good Spaghetti." |
| Rules of binomial nomenclature? | (1) Genus capitalized; (2) species epithet lowercase; (3) Latin/Latinized; (4) italicized in print; (5) underlined SEPARATELY when handwritten; (6) author name abbreviated after species. |
| Basic unit of classification? | Species — defined by interbreeding + fertile offspring. |
| Most inclusive category? | Kingdom. |
| Nine taxonomic aids? | Herbarium, Botanical Garden, Museum, Zoological Park, Key (dichotomous), Flora, Monograph, Manual, Catalogue. |
| Flora vs. Monograph? | Flora = region-based (plants in an area); Monograph = taxon-based . |
| Type specimen? | Reference specimen serving as the nomenclatural standard for a species name. |
| Taxonomy vs. Systematics? | Taxonomy = identification + nomenclature + classification. Systematics = taxonomy + evolutionary/phylogenetic relationships. Systematics is broader. |
| Phylum vs. Division? | Phylum = animals; Division = plants (equivalent rank). |
Summary (Bottom Third)
The Living World chapter establishes the foundational framework for all of biology. The key insight is that METABOLISM is the only truly universal and exclusive property of life — growth has exceptions (crystals), reproduction has exceptions (mules, worker bees), and locomotion is absent in plants. The taxonomic hierarchy (K→P→C→O→F→G→S) organises biodiversity into an increasingly specific nested framework, with Species as the basic unit and Kingdom as the most inclusive. Binomial nomenclature (Linnaeus, Systema Naturae) uses Latin two-part names with specific formatting rules — especially the separate underlining when handwritten. Nine taxonomic aids support identification and study: four specimen-based (herbarium, botanical garden, museum, zoo) and five publication-based (key, flora, monograph, manual, catalogue).
NEET Priority: Metabolism as defining feature; de Candolle vs. Linnaeus distinction; separate underlining rule; hierarchy order.
