Classification - Unveiling Life's Organization
Biological classification is a systematic approach that organizes life into hierarchies based on shared characteristics, revealing evolutionary relationships among organisms. This module explores various criteria for classification, such as cellular structure, ecological niche, and genetic data, and emphasizes the dynamic nature of classification as a tool for understanding life's complex organization. Through model organisms, learners appreciate the applications of classification in biological research and discovery.

What we have learnt
- Biological classification is essential for organizing the diversity of life based on shared characteristics.
- The hierarchy of life forms establishes increasing complexity from atoms to the biosphere.
- Classification can be based on various criteria, influencing how organisms are understood and categorized.
Key Concepts
- -- Systematics
- The field that includes classification and aims to understand evolutionary relationships among organisms.
- -- Taxonomy
- The specific branch of systematics that deals with naming and classifying organisms.
- -- Morphological Classification
- Classifying organisms based on physical form and structure.
- -- Eukaryotes
- Organisms with cells that have a membrane-bound nucleus and organelles.
- -- Prokaryotes
- Simple cellular organisms that lack a true nucleus and membrane-bound organelles.
- -- Autotrophs
- Organisms that produce their own food from inorganic substances.
- -- Heterotrophs
- Organisms that obtain food by consuming other organisms.
- -- Model Organisms
- Non-human species extensively studied to understand specific biological phenomena.
