Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

About this test

Classification of Living Things GK Quiz Level 3: Kingdoms and Groups

This Level 3 quiz is for general awareness aspirants who have revised the basics of biological classification and want application-based practice. It tests Whittaker's five kingdoms, plant groups from Thallophyta to Angiosperms, animal groups from Porifera to Vertebrata, and binomial naming. Aptitude360 explains every answer, including tricky cases such as egg-laying mammals.

What this classification of living things quiz tests

  • Whittaker's five kingdoms and the order Monera, Protista, Fungi, Plantae, Animalia
  • Prokaryotes versus eukaryotes, with examples such as bacteria, blue-green algae, Amoeba and Euglena
  • Plant groups Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms, with examples
  • Invertebrate groups such as Porifera, Coelenterata, Annelida, Arthropoda, Mollusca and Echinodermata
  • Vertebrate classes from fish to mammals, heart chambers and warm-bloodedness
  • Linnaeus, Whittaker and binomial naming rules

Key classification concepts to revise

  • Cellulose cell walls in plants and chitin cell walls in fungi
  • Lichens as a partnership of a fungus and blue-green algae
  • Crocodiles as reptiles with a four-chambered heart
  • The echidna as an egg-laying mammal, and kangaroo young born poorly developed
  • Writing scientific names: genus capitalised, species in lower case, both italicised in print

Revision tips for biological classification

  • Use the memory aid MPF-PA to fix the order of the five kingdoms.
  • Learn one standard example for each plant and animal group, such as Spirogyra, Marsilea and pine.
  • List the exceptions separately, since statement questions often test them.

Who should take this Level 3 biology GK quiz

Students preparing for general awareness sections who know the basics of classification and want a Level 3 check before final revision.

FAQs about Classification of Living Things – GK Quiz with Answers – Level 3

What are the five kingdoms of classification of living things?
Robert Whittaker grouped living things into five kingdoms: Monera, Protista, Fungi, Plantae and Animalia.
Who gave the binomial system of naming living things?
Carolus Linnaeus, a Swedish scientist, developed binomial naming. Each organism gets a genus name and a species name, and in print both words are written in italics.
Which mammals lay eggs?
The platypus and the echidna are mammals that lay eggs. They are still mammals because they have hair and feed their young on milk.
Why are blue-green algae placed in Kingdom Monera?
Blue-green algae are prokaryotes, which means their nucleus is not enclosed by a membrane. All prokaryotes, including bacteria, are placed in Monera.
