Correct option is A
Solution:
Green leaves reflect green light and absorb other wavelengths (mainly red and blue) for photosynthesis. When placed in a dark room with only green light, the following occurs:
The green light falls on the green leaves.
The leaves reflect most of that green light, making them appear brighter compared to objects that absorb green light (and appear darker).
This means the plant stands out in brightness relative to its surroundings.
Important Key Points:
Leaf Color and Light Reflection:
Green leaves reflect green wavelengths.
That’s why plants look green under normal white light.
Effect of Green Light in Darkness:
In the absence of other light, the green leaves reflect the green light, while most other materials in the surroundings absorb it.
Hence, the plant appears brighter.
Photosynthesis Efficiency:
Green light is least effective for photosynthesis.
So, the plant won’t photosynthesize actively under only green light.
Correct Option: (A) The plant appears brighter than the surroundings
