3. 3 Introduction Which of these organisms do you have the most in common with?

4. 4 Classification Organisms are divided into groups known as Domains and Kingdoms. What do you think would be the best way to classify organisms into groups? (answers will vary)

5. 5 More about Classification The classification into Domains and Kingdoms is mainly based on: Cell structure How they obtain energy How they reproduce
