Sample questions from this chapter

Which pigments dominate in Chlorophyceae?
  1. Chlorophyll a and b ✓
  2. Chlorophyll a and c with fucoxanthin
  3. Chlorophyll a and d with phycoerythrin
  4. Chlorophyll a alone in heterocysts
Answer: A. Green algae appear grass green because chlorophyll a and b dominate. Fucoxanthin is the closest trap because it is the signature accessory pigment of another algal class.
Why not B: This is the brown-algal pigment set.
Why not C: This is the red-algal pigment set.
Why not D: Heterocysts belong to cyanobacteria, which are outside Plantae here.
A marine alga has fucoxanthin, laminarin and unequal lateral flagella. It belongs to:
  1. Rhodophyceae
  2. Chlorophyceae
  3. Phaeophyceae ✓
  4. Cyanobacteria
Answer: C. Fucoxanthin, laminarin/mannitol and unequal lateral flagella diagnose Phaeophyceae. Rhodophyceae is tempting because both are predominantly marine, but red algae lack flagella.
Why not A: Red algae have phycoerythrin, floridean starch and no flagellated stages.
Why not B: Green algae have chlorophyll b, starch and equal apical flagella.
Why not D: Cyanobacteria are prokaryotes outside the three algal classes.
Assertion (A): A bryophyte sporophyte is nutritionally dependent on its gametophyte. Reason (R): The gametophyte is the photosynthetic dominant plant body.
  1. Both A and R are true, and R explains A ✓
  2. Both A and R are true, but R does not explain A
  3. A is true, but R is false
  4. A is false, but R is true
Answer: A. Both statements are true, and the photosynthetic dominant gametophyte nourishes the attached sporophyte. Treating the facts as unrelated is tempting when life-cycle stages are memorised separately.
Why not B: The gametophyte’s dominance and photosynthesis directly support the attached sporophyte.
Why not C: The bryophyte gametophyte is indeed dominant and photosynthetic.
Why not D: The sporophyte remains attached and derives nourishment.
