Classifying Living Things
📚 Part 1: Quick Check — Multiple Choice
1. What is taxonomy?
A method for measuring the age of fossils
The science of naming, defining and classifying organisms
A system for predicting weather patterns
2. Which sequence lists taxonomic ranks from most general to most specific?
Species, Genus, Family, Order, Class
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
Kingdom, Domain, Class, Order, Family
3. Check all characteristics commonly used to classify organisms:
Cell type (prokaryote or eukaryote)
DNA and genetic similarity
Habitat only (where it lives)
Visible body structures (morphology)
4. Why is a universal system of classification important?
It helps scientists communicate clearly about species
It shows evolutionary relationships between organisms
It organises biodiversity for study and conservation
All of the above
✏️ Part 2: Short Answers & Activities
