Classifying Living Things: The How and Why of the Five Kingdom Classification
Suggested Activities While Viewing the Program
1. During the 19th century, the two kingdom system was defined more scientifically. What major scientific breakthrough prompted this?
2. What change did optical microscopes bring to the scientific understanding of living organisms?
3. Why did euglena present problems with classification when it was first known about?
4. How did scientists change the classification system after the discovery of single-celled organisms, and bacteria?
5. For what reasons did it become apparent that fungi could not be placed in the plant kingdom?
6. Animals are heterotrophic. What does this mean?
7. How do most animals reproduce?

15. What are organelles?
16. How are cells of organisms placed in Kingdom Monera different?
17. What is the name given to this type of cell?
