Four Plants Grown Under Different Lights: Which Releases Oxygen Slowest?

Which of the following lights will release oxygen gas be the slowest?

A. Red

B. Blue

C. Orange

D. Green

Answer:

The release of oxygen gas would likely be slowest under orange and green lights compared to red and blue lights.

When it comes to plant growth and the release of oxygen gas through photosynthesis, the type of light the plants are exposed to plays a crucial role. Different colors of light have different effects on photosynthesis.

Plants primarily absorb blue and red light wavelengths for photosynthesis, which is why the release of oxygen gas is likely to be faster under red and blue lights. These colors of light are the most effective in stimulating photosynthesis and promoting plant growth.

On the other hand, orange and green lights are not as efficiently absorbed by plants for photosynthesis. As a result, the release of oxygen gas is expected to be slower under orange and green lights compared to red and blue lights.

Therefore, if four plants are grown under four different lights — red, blue, orange, and green — the release of oxygen gas would be slowest under orange and green lights based on the general understanding of light absorption and photosynthesis.
