Explanation of Assertion and Reason
The assertion states that members of Phaeophyceae, commonly known as brown algae, exhibit a range of colors from olive green to various shades of brown. This is an accurate observation reflecting the pigmentation in these organisms.
Understanding the Reason
The reason provided is that Phaeophyceae contain chlorophyll-a, carotenoids, and xanthophylls. These pigments are crucial for photosynthesis and contribute to the coloration of these algae.
Connection Between Assertion and Reason
- The presence of chlorophyll-a allows Phaeophyceae to capture light energy for photosynthesis.
- Carotenoids and xanthophylls, which are accessory pigments, absorb different wavelengths of light, thus influencing the overall color of the algae.
- This combination of pigments explains why members of Phaeophyceae can exhibit a range of colors, primarily brown and olive shades.
Conclusion
Given that both the assertion and the reason are true, and the reason directly explains why the assertion holds true, the correct choice is:
Option A: If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
This illustrates the relationship between the pigments present in Phaeophyceae and their color variations effectively.
