Question

Consider the following statements regarding the major pigments and stored food in the different groups of algae and select the correct options given.
A. In chlorophyceae, the stored food material is starch and the major pigments are chlorophyll a and d.
B. In phaeophyceae, laminaria is the stored food and major pigments are chlorophyll a and b.
C. In rhodophyceae, floridean starch is the stored food and the major pigments are chlorophyll a, d and phycoerythrin

• A. A is correct, but B and C are wrong.
• B. A and B are correct, but C is wrong.
• C. A and C are correct, but B is wrong.
• D. B is correct, but A and C are wrong.
• E. C is correct, but A and B are wrong.

Answer 1

Answer: (E)

C is correct, but A and B are wrong.

Green algae have chlorophylls a and b and store starch as a food reserve inside their plastids. The colours of brown algae cover a spectrum from pale beige to yellow-brown to almost black and contain such as chlorophyll c and fucoxanthin. They also lack the plasmodesmata and starch production. Rhodophytes contain chlorophyll a, which is masked by phycobilin pigments bound to proteins. The chloroplasts in red algae resemble cyanobacteria both biochemically and structurally. Food reserves are stored outside of the chloroplasts as Floridean starch.

Thus, the correct answer is option E.
