Question

Pick the option which includes all the correct statements from the following.

A. Chlorophyceae: Chlorophyll a and chlorophyll c pigments, starch-stored as food, asexual reproduction by zoospores.

B. Phaeophyceae: Fucoxanthin pigment, mannitol-stored as food, pear-shaped zoospores with 2, unequal sized apical flagella.

C. Rhodophyceae: Phycoerythrin pigment, floridean starch, reproduction by non-motile spore.

• A. A, B and C
• B. Only A
• C. Only B
• D. Only C

Answer 1

The correct option is D Only C

Rhodophyceae include all red algae. They are red due to the presence of the pigment phycoerythrin. They store their reserve food material in the form of floridean starch. They reproduce asexually by non-motile spores.

Chlorophyceae include all green algae. They have chlorophyll a and chlorophyll b pigments.

Phaeophyceae include all brown algae. They have pear-shaped zoospores with 2 unequal sized flagella. But the flagella are lateral and not apical.
