Classification into kingdoms and domains: sub-cellular evidence
I can describe the classification of organisms based on evidence from their phenotype and cells.
Classification into kingdoms and domains: sub-cellular evidence
I can describe the classification of organisms based on evidence from their phenotype and cells.
Lesson details
Key learning points
- Organisms are classified into groups within larger groups, from species up to kingdoms and domains
- There are domains of eukaryotes (animals, plants, fungi and protists), bacteria and archaea (both prokaryotic)
- Organisms can be classified using evidence of their macroscopic features (phenotype)
- Organisms can be classified using evidence of their and microscopic cell structures
Common misconception
Pupils may think that the modern classification system that we use today is complete.
Remind pupils why new data from experiments or observations leads to changes in models or theories.
Keywords
