Deepest algae in sea are
Open in App
Solution
The correct option is A Red algae
Red algae have red pigment phycoerythrin which carries out photosynthesis using only short wavelength light found in greater depth.
Sunlight is broken into its component colour as it penetrates into ocean, longer wavelengths are weak hence, cannot penetrate deep in sea while shorter wavelength do.
Other options:
Option B: Brown algae are mostly marine, including seaweeds. Sargassum has a unique habitat of tropical seashores. Many brown algae grow along rock seashores.
Option C: Green algae are common in areas where light is abundant such as shallow water and tide pools.
Option D: Golden algae (Chrysophyceae) are present in both fresh and marine water. Thus, the correct answer is option A.
