Red algae are photosynthetic organisms that are adapted to live in deep marine environments where only certain wavelengths of light can penetrate.
A researcher studied red algae under different light conditions and made the following observations:
Which of the following statements correctly explains these observations?
The pigments in red algae absorb red light, and light intensity is a limiting factor for the rate of photosynthesis.
The pigments in red algae absorb blue-green light, and light intensity is a limiting factor for the rate of photosynthesis.
The pigments in red algae absorb red light, and light intensity is not a limiting factor for the rate of photosynthesis.
The pigments in red algae absorb blue-green light, and light intensity is not a limiting factor for the rate of photosynthesis.
