WHAT IS CLASSIFICATION? CLASSIFICATION IS grouping things according to similar characteristics (Examples of characteristics are size, shape, color, behavior, etc…) Biological classification systems name & organize living things in a logical and meaningful way.

DEFINITIONS Taxonomy: the study or practice of classifying living things Basis of a classification/taxonomic system: the characteristic that is used to decide what things are placed in which groups during the process of classification

History of Classification 1) Aristotle: A. Lived around the year of 384 BC B. Designed a classification system for organisms 1. The basis of his taxonomic system was the characteristic of movement. 2. First: He divided ALL living things into two groups/kingdoms: Those that can move from place to place Those that cannot move from place to place ANIMALS PLANTS 3. Second: He divided the group called animals (can move) into 3 groups according to the way they moved: fly, walk, swim

History of Classification 2) Today’s system: A. Basis of today’s system: similarity of structure (ex.: skin covering, DNA) B. The system used today has 5 kingdoms. Listed from the kingdom of the simplest organisms to the kingdom of the most complex organisms, these 5 kingdoms are: 1) Moneran Kingdom (simplest organisms) 2) Protist Kingdom 3) Fungi Kingdom 4) Plant Kingdom 5) Animal Kingdom (most complex organisms)

Classification – definitions – Part A 1) unicellular: made of one cell 2) multicellular: made of more than one cell 3) autotroph: an organism that gets its energy by making its food in its body 4) heterotroph: an organism that gets its energy by eating other organisms

Characteristics of living things: 1. Living things are made of cells. 2. Living things use energy 3. Living things grow and develop. 4. Living things respond to the environment. 5. Living things reproduce.
