Biology Test: Ultimate Trivia Questions Quiz

What do you know about biology? Could you pass a biology test? There are so many different essential terms in biology. These include prokaryotes, which are three domain systems of application. A prokaryote is a one-cell organism that does not have a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. This quiz will help you discover how much you understand about biology.


Questions and Answers
  • 1. 
    Prokaryotes
    • A. 

      Are currently classified in the domain Monera

    • B. 

      Comprise a monophyletic group

    • C. 

      Are single-celled protists

    • D. 

      Are in the domains Bacteria and Archaea

    • E. 

      Are cells with organelles but no nucleus

  • 2. 
    Given the 3 domain system of classification, Prokaryotes are not monophyletic because
    • A. 

      Prokaryotes evolved earlier than Eukarya

    • B. 

      Archaea share a more recent common ancestor with the Eukarya than with the Bacteria

    • C. 

      Bacteria and Archaea are not prokaryotes

    • D. 

      Bacteria are more closely related to Eukarya than Archaea

    • E. 

      All of the above are true

  • 3. 
    Assuming the first Eukarya gave rise to all the lineages of "Protista", Protista could be made monophyletic if
    • A. 

      It was given its own domain

    • B. 

      It included the plants, fungi and animals

    • C. 

      If it only included single celled eukaryotic and prokaryotic organisms

    • D. 

      It included all photosynthetic organisms

    • E. 

      It also included Archaea and all of its descendants

  • 4. 
    What is TRUE about cyanobacteria?
    • A. 

      The oxygen catastrophe led to their extinction, and they didn't survive to the present day

    • B. 

      They are considered extremophiles from the Domain Archaea

    • C. 

      Some entered into an endosymbiotic relationship with other cells; a relationship that led to what we call plants today

    • D. 

      We currently recognize them as single celled protists

    • E. 

      All are true statements about cyanobacteria

  • 5. 
    Which cells or organelles were the earliest contributors to increasing oxygen availability in the atmosphere?
    • A. 

      Chloroplasts

    • B. 

      Mitochondria

    • C. 

      Algae

    • D. 

      Cyanobacteria

    • E. 

      Photosynthetic protists

  • 6. 
    Place the following terms in the correct sequence of events in the evolution of life on Earth (from earliest to most recent). 1. Mitochondria 2. Multicellular eukaryotes 3. Chloroplasts 4. Cyanobacteria 5.  Plant symbioses with fungi
    • A. 

      1--4--3--5--2

    • B. 

      1--3--2--4--5

    • C. 

      4--1--3--2--5

    • D. 

      4--2--3--1--5

    • E. 

      2--3--1--5--4

  • 7. 
    All of these are examples of evidence used to support the hypothesis of endosymbiosis, EXCEPT:
    • A. 

      Mitochondria and plastids contain circular DNA molecules similar to the circular chromosomes of bacteria

    • B. 

      Mitochondria and plastids, like prokaryotes, only contain genetic material in the form of RNA

    • C. 

      Mitochondria and plastids can replicate themselves in a process similar to prokaryotes

    • D. 

      Mitochondria and plastids have their own ribosomes and enzymes that can be used to transcribe and translate DNA into proteins

    • E. 

      Mitochondria and plastids have a double membrane (inner and outer)

  • 8. 
    According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate?
    • A. 

      from the nuclear envelope folding inward and forming mitochondrial membranes

    • B. 

      from engulfed, originally free-living prokaryotes

    • C. 

      from genetic mutations that caused an infolding of the cell wall of a prokaryote

    • D. 

      from the adaptation of the nucleus to produce energy

    • E. 

      From a symbiotic relationship between cyanobacteria and a protist

  • 9.
