Parasitology

Step 1: Understanding food storage in algae Chlorophyceae stores food in the form of pyrenoids, which are proteinaceous bodies associated with starch storage.
Phaeophyceae stores food as mannitol, not pyrenoids.
Rhodophyceae stores food as Floridean starch, not pyrenoids.
Step 2: Evaluating the options Option (1): Incorrect, as Chlorophyceae does not store starch directly.
Option (2): Incorrect, as Phaeophyceae stores food as mannitol.
Option (3): Incorrect, as Rhodophyceae stores food as Floridean starch.
Option (4): Correct, as Chlorophyceae stores food in pyrenoids.
Final Answer:
