(c) Asexual reproduction occurs by non-motile spores. (d) It shows dominance of chlorophyll a, c and fucoxanthin. (e) Sexual reproduction is oogamous with complex post-fertilization developments. Choose the correct answe
Options
- A(a), (b) and (c) only
- B(a), (c) and (e) only
- C(b), (d) and (e) only
- D(c), (d) and (e) only
Correct answer
B. (a), (c) and (e) only
Step-by-step solution
The given diagram represents Polysiphonia , a red alga belonging to the class Rhodophyceae. Statement (a) is correct as it is a member of Rhodophyceae. Statement (b) is incorrect because red algae store food as floridean starch, whereas mannitol and laminarin are stored in brown algae (Phaeophyceae). Statement (c) is correct because asexual reproduction in red algae occurs via non-motile spores. Statement (d) is incorrect because red algae contain chlorophyll a, d, and phycoerythrin. Chlorophyll a, c, and fucoxanth
