Question

Choose the correct match.

• A. Phaeophyceae - mannitol, chlorophyll a, c
• B. Rhodophyceae - floridean starch, chlorophyll a, d
• C. Chlorophyceae - starch, chlorophyll a, b
• D. Rhodophyceae - mannitol, chlorophyll a, d

Answer 1

Answer: (A), (B), (C)

The correct options are
A Phaeophyceae - mannitol, chlorophyll a, c
B Rhodophyceae - floridean starch, chlorophyll a, d
C Chlorophyceae - starch, chlorophyll a, b

Rhodophyta are commonly called red algae because of the predominance of the red pigment, r-phycoerythrin in their body. Chlorophyll a and d are found in this class of algae. The food is stored as floridean starch. The members of Phaeophyceae or brown algae possess chlorophyll a, c, carotenoids, and xanthophylls. Food is stored as complex carbohydrates, which may be in the form of laminarin or mannitol. The members of Chlorophyceae are commonly called green algae. They are usually grass green due to the dominance of pigments chlorophyll a and b. Main food stored is starch.
