- Characteristics of living beings:
Growth → Reproduction → Metabolism → Cellular Organisation → Consciousness → Interactions - In binomial nomenclature, each name has two components, a generic name and a specific epithet.

Species → Genus → Family → Order → Class → Phylum/Division → Kingdom - Certain procedures and techniques are practised in order to store or preserve this information. These procedures are called taxonomical aids.
- Herbarium is a storehouse of collected plant specimens which are dried, pressed and preserved on sheets.
- Botanical gardens are specialised gardens which have collections of living plants for reference.
- Museums have collections of preserved plant and animal specimens for study and reference.
