Lesson Worksheet: Kingdom Monera Biology

In this worksheet, we will practice describing the characteristics of organisms belonging to the kingdom Monera, recalling the divisions of kingdom Monera as Eubacteria and Archaebacteria, and applying knowledge of these divisions to classify given organisms correctly.

Q1:

Which of the following correctly describes the difference between the cell walls of Archaebacteria and Eubacteria?

  • AEubacteria have cell walls that are composed of peptidoglycan, which is not present in Archaebacteria cell walls.
  • BArchaebacteria have cell walls that are composed of peptidoglycan, which is not present in Eubacteria cell walls.

Q2:

By what method do organisms belonging to kingdoms Archaebacteria and Eubacteria commonly reproduce?

  • ABinary fission
  • BMeiosis
  • CProduction of spores
  • DMitosis

Q3:

Which of the following correctly describes the difference between the environments of Archaebacteria and Eubacteria?

  • AMany species of Eubacteria are extremophiles and live in extreme environments, whereas Archaebacteria are found in all environments.
  • BMany species of Archaebacteria are extremophiles and live in extreme environments, whereas Eubacteria are found in all environments.

Q4:

Fill in the blank:

The genetic material of organisms in the kingdom Monera is largely contained within a circular .

  • Anucleus
  • Bnucleosome
  • Cgene
  • Dchromosome

Q5:

Fill in the blank:

The majority of organisms belonging to kingdom Monera are .

  • Aunicellular
  • Bbicellular
  • Cmulticellular
  • Dnoncellular

Q6:

Which of the following is a characteristic of an organism belonging to kingdom Monera?

  • AMost of these organisms are large and multicellular.
  • BThe cells of these organisms contain a cellulose cell wall.
  • CThese organisms only reproduce sexually.
  • DThe cells of these organisms do not contain a membrane-bound nucleus.

Q7:

In 1977, biologist Carl Woese proposed a new six-kingdom system of classification that split kingdom Monera into two new kingdoms. What two kingdoms was kingdom Monera split into?

  • AEubacteria and Archaebacteria
  • BEubacteria and Prokaryota
  • CProtista and Prokaryota
  • DProtista and Archaebacteria

Q8:

Fill in the blank:

Almost all Eubacteria and Archaebacteria posses .

  • Aa circular nucleus
  • Bextended cilia
  • Ca cellulose membrane
  • Da cell wall

Q9:

A unicellular organism has been discovered. The organism is adapted to survive in hot springs that have very high temperatures and low pH levels. Which taxonomic group, Archaebacteria or Eubacteria, is this organism most likely to belong to?

  • AArchaebacteria
  • BEubacteria

Q10:

A unicellular organism has been discovered. The organism usually resides in the human gut and requires access to oxygen to survive. Which kingdom, Archaebacteria or Eubacteria, is this organism most likely to belong to?

  • AArchaebacteria
  • BEubacteria
