Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Four identical plants are grown under different colored light bulbs. Under which color will the release of oxygen gas be the slowest?
A
Blue
B
Orange
C
Green
D
Red
Explanation: 

Detailed explanation-1: -Plants under yellow & green light will carry out photosynthesis at a lower rate than the same type of plant under other colors (blue, violet, red).

Detailed explanation-2: -Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture.

Detailed explanation-3: -Green produced a total of 6.09 milliliters of oxygen, red produced 3.96 milliliters of oxygen, yellow produced 2.89 milliliters of oxygen, clear produced 2.17 milliliters of oxygen, and lastly blue produced 1.71 milliliters of oxygen. I conclude that the blue light stimulates chlorophyll the best.

Detailed explanation-4: -So, when only green light is provided to the plant all of it is reflected and no light is present to perform the process of photosynthesis due to which the rate of the same declines, and with it, the flow of oxygen also declines.
