Effects of Different Colored Light Bulbs on Oxygen Gas Release in Plants

Which colored light bulb will result in the slowest release of oxygen gas in plants?

A. Blue

B. Orange

C. Green

D. Red

The release of oxygen gas will be the slowest under which colored light bulb?

The release of oxygen gas will be the slowest under the red colored light bulb.

Four identical plants are grown under different colored light bulbs to observe the effects on oxygen gas release. It is found that the release of oxygen gas will be the slowest under the red colored light bulb.

Phycoerythrin, a red pigment present in cryophytes and red algae, reflects red light. This pigment is essential for the main chlorophyll pigments required for photosynthesis. Therefore, the release of oxygen gas is hindered under the red colored light bulb due to the reflection of red light by phycoerythrin.

In conclusion, the correct option for the colored light bulb resulting in the slowest release of oxygen gas in plants is option D - Red.
