Understanding the Assertion and Reason
The assertion and reason provided in the question require a detailed analysis to determine their validity.
Assertion (A):
- Algae are classified into three main classes based on the type of pigment and stored food they possess.
- This statement is true. Algae are commonly categorized into three major groups: Chlorophyta (green algae), Rhodophyta (red algae), and Phaeophyta (brown algae). The classification is indeed based on the pigments they contain (such as chlorophylls and carotenoids) and the type of food they store (like starch or other carbohydrates).
Reason (R):
- Algae reproduce exclusively through vegetative methods, such as fragmentation.
- This statement is false. While algae can reproduce vegetatively through methods such as fragmentation, they also reproduce sexually (through gametes) and asexually (through spores). Therefore, the claim that their reproduction is exclusively vegetative is incorrect.
Conclusion
- Since the assertion is true and the reason is false, the correct option is (c): If Assertion is true but Reason is false.
- This distinction is crucial for understanding the classification and reproduction methods of algae, which are diverse and not limited to only vegetative means.
In summary, algae's classification is accurately described, while the reason presented about their reproduction is misleading.

  • Assertion: True. Algae are classified into Chlorophyceae, Phaeophyceae, and Rhodophyceae, primarily based on differences in their pigment composition and type of stored food, such as starch, mannitol, or laminarin.
  • Reason: False. While vegetative reproduction like fragmentation is a common method among algae, it is incorrect to state that algae reproduce exclusively through such methods. Algae can also reproduce asexually through spores and sexually through various types of gametes and reproductive strategies (isogamous, anisogamous, oogamous).
  • Therefore, the Assertion is correct, but the Reason is false, making Option C the correct choice.
