Class 11 · Chapter 1The Living World

Kingdom → Phylum → Class → Order → Family → Genus → Species: “King Philip Came Over For Good Soup”.

1. What is Living?

  • Defining features: metabolism, cellular organisation, consciousness (response to stimuli).
  • Growth and reproduction are not defining (crystals grow; mules don't reproduce).

2. Binomial Nomenclature

  • Given by Carolus Linnaeus: Genus (capital) + species epithet (small).
  • Printed in italics; underlined separately when handwritten.
  • Example: Mangifera indica Linn.

Codes: ICBN (plants), ICZN (animals).

4. Taxonomic Aids

Herbarium

Dried, pressed, preserved plant specimens on sheets.

Botanical garden

Living plants (e.g. Kew, Indian Botanical Garden Howrah).

Museum

Preserved specimens in jars, stuffed animals.

Key

Contrasting couplets (leads) used for identification.

Also: zoological parks, flora, manuals, monographs, catalogues.

5. Key Points

  • Species is the basic unit of classification.
  • Taxonomy = identification, nomenclature, classification.
  • Systematics also covers evolutionary relationships.
  • Higher rank ⇒ fewer common features.

Remember: Metabolism defines life | binomial rules | 7 ranks
