Food storage molecules in algae across the three classes are:
AChlorophyceae: Starch; Phaeophyceae: Mannitol/Laminarin; Rhodophyceae: Floridean starch
BAll three store cellulose
CChlorophyceae: Mannitol; Phaeophyceae: Floridean starch; Rhodophyceae: Glycogen
DAll three store oil droplets only
Answer & Solution
Correct answer: A. Chlorophyceae: Starch; Phaeophyceae: Mannitol/Laminarin; Rhodophyceae: Floridean starch
Chlorophyceae (green) — starch; Phaeophyceae (brown) — laminarin or mannitol; Rhodophyceae (red) — floridean starch (similar to amylopectin/glycogen). Option B inverts the assignments.
