Questions and Answers
What was Aristotle's contribution to the classification of living organisms?
Aristotle used simple morphological characters to classify plants and animals based on their physical characteristics and blood color.
What was the Two Kingdom system of classification developed by Linnaeus?
The Two Kingdom system included the Plantae kingdom for plants and the Animalia kingdom for animals.
What were the limitations of the Two Kingdom system of classification?

Study Notes
Aristotle's Contribution to Classification
- Aristotle's classification of living organisms was based on simple observations and was not systematic.
- He classified plants and animals into two categories: plants and animals.
Linnaeus' Two Kingdom System of Classification
- Carl Linnaeus developed the Two Kingdom system of classification, which divided living organisms into two kingdoms: Animalia and Plantae.
- This system was used for over 200 years and laid the foundation for modern biological classification.
Limitations of the Two Kingdom System
- The Two Kingdom system failed to recognize the diversity of microorganisms and fungi.
- It did not provide a clear distinction between single-celled and multi-celled organisms.
Purpose of Biological Classification
- The purpose of biological classification is to group organisms into categories based on their shared characteristics and evolutionary relationships.
Criteria for Modern Scientific Classification
- Morphology (shape and structure)
- Anatomy (internal organization)
- Embryology (developmental stages)
- Physiology (functions and processes)
- Biochemistry (chemical composition)
- Molecular biology (genetic information)
Five Kingdoms of Biological Classification
- Monera (bacteria and other single-celled organisms)
- Protista (single-celled eukaryotes, including protozoa and algae)
- Fungi (mushrooms, molds, and yeasts)
- Plantae (plants)
- Animalia (animals)
Aristotle's Scientific Basis
- Aristotle's classification of plants and animals was based on simple observations and was not systematic.
Limitations of the Two Kingdom System
- Failed to recognize the diversity of microorganisms and fungi.
- Did not provide a clear distinction between single-celled and multi-celled organisms.
Early Civilizations' Attempts at Classification
- Early civilizations, such as the Greeks, Romans, and Chinese, made attempts to classify living organisms based on their characteristics and uses.
