Classifying Organisms

Science · Ecosystems & Habitats · conceptual

Describe how living things are classified into broad groups (micro-organisms, plants, animals) according to common observable characteristics, similarities, and differences

What mastery looks like

  • Name the broad classification groups: micro-organisms, plants, animals (and fungi if known)
  • Describe observable characteristics used for classification (e.g. plants make own food, animals move and eat)
  • Give examples of organisms in each group, including micro-organisms like bacteria

Check your understanding

Can Classifying Organisms explain the big groups that scientists sort all living things into — like plants, animals, and tiny micro-organisms — and give examples of each?
