Consider the following statements regarding the major pigments and stored food in the different groups of algae and select the correct options given.

1. In chlorophyceae, the stored food material is starch and the major pigments are chlorophyll a and d.
2. In phaeophyceae, laminaria is the stored food and major pigments are chlorophyll a and b.
3. 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.
4. B is correct, but A and C are wrong. E. \( C \) is correct, but \( A \) and \( B \) are wrong

Correct answer: 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.

Solution

Chlorophyceae store starch and mainly have chlorophyll a and b, so A is incorrect. Phaeophyceae store laminarin and mannitol, not laminaria, and their pigments are chlorophyll a and c, so B is incorrect. Rhodophyceae do store floridean starch and contain chlorophyll a, d, and phycoerythrin, so C is correct.
