Worked practice questions

Whittaker (1969) proposed how many kingdoms in biological classification?

  1. 3
  2. 2
  3. 5 (Monera, Protista, Fungi, Plantae, Animalia)
  4. 7
Show answer and solution

Correct answer: C. 5 (Monera, Protista, Fungi, Plantae, Animalia)

R.H. Whittaker's 5-kingdom system: Monera (prokaryotes), Protista (single-celled eukaryotes), Fungi (multicellular decomposers), Plantae (multicellular photoautotrophs), Animalia (multicellular heterotrophs). Based on cell structure, body organization, mode of nutrition, reproduction, phylogeny.

Halophiles thrive in:

  1. Hot
  2. Cold
  3. Random
  4. High salt environments (e.g., salt lakes, salt flats)
Show answer and solution

Correct answer: D. High salt environments (e.g., salt lakes, salt flats)

**Halophiles:** salt-loving extremophiles. Live in Dead Sea, Great Salt Lake, brines (>30% NaCl). Mostly archaea (Halobacterium). Use compatible solutes to balance osmotic pressure. Color salterns red/pink (bacterioruberin pigments). **Bacteriorhodopsin:** ATP-generating proton pump driven by light.
