Q. Artificial light can
Photosynthesis is the process by which green plants use light energy to convert carbon dioxide and water into glucose and oxygen. While sunlight is the natural source of light for photosynthesis, artificial light (such as LED, fluorescent, or grow lights) can also provide the necessary wavelengths (red and blue light) required for the process.
This is why indoor plants and hydroponic farming use artificial lighting to support plant growth in environments where natural sunlight is limited.
Why not the other options?
- (B) Destroy chlorophyll → Artificial light does not destroy chlorophyll; intense heat or ultraviolet rays might.
- (C) Not bring about photosynthesis → Incorrect, as plants can photosynthesize under artificial light.
- (D) Synthesize chlorophyll → Chlorophyll synthesis is influenced by light, but it requires other biological processes as well.
Thus, the correct answer is (A) Bring about photosynthesis.
