19. Fungus: unicellular or multicellular eukaryote that is stationary, absorbs nutrients from organic materials in the environment, and has cell walls that contain chitin
20. Protist: unicellular, multicellular, or colonial eukaryote whose cell walls may contain cellulose; can be plant-like, animal-like, or fungus-like
17.1 ASSESSMENT QUESTIONS:
1. It is easier to communicate and retain information about organisms when they are categorized into groups.
2. In the name given to an organism according to binomial nomenclature, the first part is the genus name, and the second part is the specific epithet, or specific name, that identifies the species.
3. In modern classification systems, people could classify organisms not only on morphological and behavioral characteristics, but also included evolutionary relationships.
4. The giant panda is of the Animalia Kingdom, Chordata Phylum, Mammalia Class, Carnivora Order, Ursidae Family, Ailuropoda Genus and Melanoleuca Species.
5. Since the phyla includes multiple classes, there would be more biodiversity in the phylum than in the class.
6. Taxonomy involves classifying species, but systematics involves discovering new species and relationships. They incorporate information from taxonomy in their studies.
