Mistake 1: Choosing growth or reproduction as the defining feature of life Correction: Metabolism is the correct answer. Growth has the crystal exception; reproduction has the mule/worker bee/infertile human exception. Metabolism has NO exception.

Mistake 2: Confusing who coined "taxonomy" vs. who established "binomial nomenclature" Correction: "Taxonomy" was coined by A.P. de Candolle. Binomial nomenclature was established by Carolus Linnaeus (Systema Naturae). Students frequently mix these two attributions.

Mistake 3: Underlining the scientific name as one continuous line when handwritten Correction: Each word (genus and species) must be underlined separately. Homo and sapiens get two distinct underlines — not one line beneath both words together.

Mistake 4: Using "Phylum" for plants and "Division" for animals Correction: Phylum is used for animals; Division is used for plants. This is commonly reversed in MCQs.

Mistake 5: Thinking the species is the most inclusive taxonomic category Correction: Species is the LEAST inclusive (most specific). Kingdom is the MOST inclusive category.

Mistake 6: Thinking that Flora and Monograph mean the same thing Correction: Flora is region-based (describes all plant species in a geographical area). Monograph is taxon-based (detailed study of one genus or family, regardless of location).

Mistake 7: Writing genus name in lowercase or species name with a capital letter Correction: Genus name — first letter capitalised (Homo). Specific epithet — all lowercase (sapiens). Getting this inverted is a classic trap in naming-convention MCQs.

Mistake 8: Thinking systematics and taxonomy are identical Correction: Taxonomy is a subset of systematics. Systematics adds the dimension of evolutionary/phylogenetic relationships — it is the broader science.
