Worked practice questions

Algae are divided into THREE main classes:

  1. Liverworts, Mosses, Ferns
  2. Cycas, Pinus, Ginkgo
  3. Bryophytes, Pteridophytes, Gymnosperms
  4. Chlorophyceae, Phaeophyceae, Rhodophyceae
Show answer and solution

Correct answer: D. Chlorophyceae, Phaeophyceae, Rhodophyceae

The three classes of algae are Chlorophyceae (green algae), Phaeophyceae (brown algae) and Rhodophyceae (red algae). Bryophytes/Pteridophytes/Gymnosperms are higher plant groups liverworts/mosses are bryophytes Cycas/Pinus/Ginkgo are gymnosperms.

AGAR — used for microbiology media and ice creams — is commercially obtained from:

  1. Red algae — Gelidium and Gracilaria
  2. Green algae — Chlorella, Ulothrix
  3. Brown algae (Sargassum, Laminaria)
  4. Bryophytes — Sphagnum
Show answer and solution

Correct answer: A. Red algae — Gelidium and Gracilaria

Agar comes from red algae Gelidium and Gracilaria. Brown algae yield algin (hydrocolloid) red algae also yield carrageen. Chlorella (green) is a protein food supplement. Sphagnum yields peat.

Pteridophytes that produce TWO KINDS of spores (macro and micro spores) are called:

  1. Heterosporous — e.g. Selaginella and Salvinia
  2. Homosporous (all spores similar)
  3. Isosporous
  4. Aposporous
Show answer and solution

Correct answer: A. Heterosporous — e.g. Selaginella and Salvinia

Most pteridophytes are homosporous (one kind of spore). Selaginella and Salvinia are HETEROSPOROUS — produce megaspores and microspores that develop into female and male gametophytes respectively. This precedes the seed habit.
