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
  • EBoth prions and dinoflagellates

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
