Different living things have key distinguishing anatomical and physiological characteristics. Within each domain and kingdom are species with similar characteristics. They can be classified using a dichotomous key.

Task: Make a dichotomous key that demonstrates your understanding of the breadth of different domains or kingdoms studied in this course. Include specific examples in your dichotomous key if necessary.

Answer :

Answer:

Explanation:

Here is a dichotomous key showcasing the breadth of different domains and kingdoms studied in this course:

1. Does the organism have a nucleus in its cells? (go to 2 if yes, go to 3 if no)

2. Is the organism unicellular or multicellular?

- Unicellular: belongs to the domain Bacteria (e.g. E. coli)

- Multicellular: go to 3

3. Does the organism have a cell wall made of chitin? (go to 4 if yes, go to 5 if no)

4. Belongs to the kingdom Fungi (e.g. mushrooms)

5. Does the organism obtain energy through photosynthesis? (go to 6 if yes, go to 7 if no)

6. Belongs to the kingdom Plantae (e.g. sunflower)

7. Does the organism have a cell wall made of cellulose? (go to 8 if yes, go to 9 if no)

8. Belongs to the kingdom Protista (e.g. amoeba)

9. Does the organism have unique metabolic processes such as methanogenesis or halophily? (go to 10 if yes, go to 11 if no)

10. Belongs to the domain Archaea (e.g. Methanobrevibacter smithii)

11. Does the organism have a backbone or spinal cord? (go to 12 if yes, go to 13 if no)

12. Belongs to the kingdom Animalia (e.g. humans)

13. Belongs to the domain Eukarya but does not fit into any of the above kingdoms (e.g. slime molds).
