Biological Classification — Class 11 CBSE Biology revision notes
A 5-page visual revision sheet for Biological Classification, written for Class 11 CBSE Biology. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.

Biological Classification in one look
one kingdom becomes five, sorted by cell, food and body plan
Whittaker's five kingdom system, 1969
- replaced the old two-kingdom scheme, which forced bacteria and fungi awkwardly into "plants"
- every organism now sorts into Monera, Protista, Fungi, Plantae or Animalia
- the split rests on five criteria used together, never any one alone
Five criteria behind the split
- Cell structure: prokaryotic or eukaryotic, a defined nucleus or none
- Body organisation: unicellular or multicellular, level of thallus organisation
- Mode of nutrition: autotrophic or heterotrophic
- Mode of reproduction: asexual or sexual
- Phylogenetic relationships: the evolutionary ancestry linking the groups
The five kingdoms, one line each
- Monera: prokaryotic, no nuclear membrane
- Protista: unicellular eukaryotes, a boundary group
- Fungi: heterotrophic, absorptive, cell wall of chitin
- Plantae: autotrophic, cell wall of cellulose
- Animalia: heterotrophic, no cell wall at all

How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Biology chapter by chapter against your real exam dates and free hours, and when the plan reaches Biological Classification the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
