Lesson Worksheet: Systems of Classification Biology
In this worksheet, we will practice describing the classification systems proposed by Linnaeus and Whittaker and recalling organisms that are difficult to classify.
Q1:
Robert H. Whittaker classified organisms into 5 kingdoms. What were these kingdoms?
- AEukaryota, Plantae, Animalia, Aves, Reptilia
- BMonera, Protista, Fungi, Plantae, Animalia
- CChordata, Fungi, Plantae, Animalia, Protostomes
- DMammalia, Aves, Reptilia, Amphibia, Fish
- EMonera, Protista, Fungi, Plantae, Mammalia
Q2:
Which of the following correctly compares Linnaeus’s and Whittaker’s systems of classification?
- AWhittaker had more biological and technological knowledge when creating his system of classification.
- BLinnaeus had more biological and technological knowledge when creating his system of classification.
Q3:
Why is it difficult to classify viruses into Whittaker’s system of classification?
- ABecause Whittaker’s system did not include classification of microorganisms
- BBecause they have very few defining features
- CBecause they were discovered after Whittaker created his system of classification
- DBecause they share characteristics with both Kingdom Plantae and Kingdom Fungi
- EBecause they are generally considered to be nonliving
Q4:
Which of the following cannot be classified into a kingdom in Whittaker’s system of classification?
- AHumans
- BBacteria
- CYeast
- DPrions
- EArchaea
Q5:
Carl Linnaeus classified organisms into two distinct groups. What were these groups?
- AThe animal kingdom and the plant kingdom
- BLiving and nonliving
- CKingdom Mammalia and kingdom Plantae
- DArtificial and natural
- EInvertebrates and vertebrates
Q6:
Which of the following is not a true example of a living organism?
- APrions
- BNostoc
- CDinoflagellates
- DMalaria parasites
Q7:
Which of the following best explains why coronavirus is not classified in any of the five kingdoms of Whittaker's system of classification?
- ACoronavirus is a new type of living organisms that we still do not have enough information about to be able to classify it within the kingdoms of Whittaker's system of classification.
- BUnlike all other classified organisms, coronavirus was discovered years after Whittaker's death.
- CCoronavirus, like all other types of viruses, has not been completely classified as a living or nonliving organism.
- DCoronavirus cannot be classified with the other similar prokaryotes because it is a unicellular prokaryote that shares some characteristics with protists.
Q8:
Which of the following correctly compares Linnaeus’s and Whittaker’s systems of classification?
- ALinnaeus’s classification was introduced two centuries after Whittaker’s system of classification.
- BLinnaeus laid the groundwork for a system of classification that Whittaker completed two centuries later.
Q9:
Biological classification is a science that establishes a hierarchical system of categories of organisms. What is this science commonly called?
- AGenealogy
- BEcology
- CPhysiology
- DTaxonomy
- EEmbryology
Q10:
On which primary basis were organisms initially classified together in Linnaeus’s and Whittaker’s classifications?
- ASharing observable, physical characteristics
- BHaving predator–prey relationships
- CSharing the same food
- DSharing the same habitat
