Worked practice questions

Algae are BEST characterised as

  1. Non-chlorophyllous, complex, fully terrestrial heterotrophs
  2. Chlorophyll-bearing, vascular, exclusively terrestrial autotrophs
  3. Non-photosynthetic, simple, parasitic micro-organisms only
  4. Chlorophyll-bearing, simple, thalloid, largely aquatic autotrophs
Show answer and solution

Correct answer: D. Chlorophyll-bearing, simple, thalloid, largely aquatic autotrophs

Section 3.1 your syllabus: algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic. They span fresh, marine and damp-habitat forms.

The three principal classes of algae are

  1. Chlorophyceae, Phaeophyceae, Rhodophyceae
  2. Bryophyta, Pteridophyta, Spermatophyta
  3. Liverworts, Mosses, Hornworts
  4. Psilopsida, Lycopsida, Sphenopsida
Show answer and solution

Correct answer: A. Chlorophyceae, Phaeophyceae, Rhodophyceae

Algae are divided into three classes by pigment composition and stored food: green (Chlorophyceae), brown (Phaeophyceae) and red (Rhodophyceae). Table 3.1 your syllabus.

Green algae owe their colour mainly to

  1. Fucoxanthin and xanthophyll only
  2. Anthocyanin and beta carotene
  3. Chlorophyll a and b pigments
  4. Phycoerythrin and r-phycocyanin
Show answer and solution

Correct answer: C. Chlorophyll a and b pigments

Chlorophyceae are grass-green because chlorophylls a and b dominate. Phycoerythrin colours red algae fucoxanthin colours brown algae anthocyanins are flower pigments.
