Worked practice questions

Carolus Linnaeus is best known as the father of:

  1. Modern genetics (Mendel's predecessor)
  2. Evolutionary biology (Darwin's predecessor)
  3. Modern taxonomy and binomial nomenclature
  4. Cell biology (Hooke's successor)
Show answer and solution

Correct answer: C. Modern taxonomy and binomial nomenclature

Carolus Linnaeus (1707-1778) is the FATHER OF MODERN TAXONOMY. His 'Systema Naturae' introduced binomial nomenclature. Mendel founded genetics; Darwin/Wallace founded evolutionary biology.

The cell wall of bacteria (Kingdom MONERA) is made primarily of:

  1. Peptidoglycan (also called murein)
  2. Chitin (a polysaccharide, like crab shell)
  3. Cellulose (the plant cell wall component)
  4. Pseudopeptidoglycan (in archaea only)
Show answer and solution

Correct answer: A. Peptidoglycan (also called murein)

True bacteria (Eubacteria) have cell walls of PEPTIDOGLYCAN (murein). Archaea have pseudopeptidoglycan or other compositions. Fungi have chitin. Plants have cellulose. Animals have no cell wall.

Mushrooms belong to which class of FUNGI?

  1. Phycomycetes (e.g. Rhizopus moulds)
  2. Basidiomycetes (mushrooms, puffballs)
  3. Ascomycetes (e.g. yeasts, Penicillium)
  4. Deuteromycetes (imperfect fungi)
Show answer and solution

Correct answer: B. Basidiomycetes (mushrooms, puffballs)

Mushrooms, puffballs, bracket fungi all belong to BASIDIOMYCETES (so-called 'club fungi'). Reproduce via basidiospores on basidia. Phycomycetes = algal-like Ascomycetes = yeast + moulds Deuteromycetes = sexual stage unknown.
