Quick Answer: Which Light Range Is Least Effective In Photosynthesis A Blue B Green C Red D Violet?

Is it better to grow plants under blue and red light?

Effects of Blue Light on Plants By Erik Runkle.


In contrast, blue light is considered equally effective as green or red light at driving photosynthesis.

Thus, while blue light can appear somewhat dim to us, it has high energy and is useful for plant growth applications..

Which of the following is least effective in photosynthesis?

Maximum photosynthesis takes place in red and blue light of the visible spectrum and minimum photosynthesis takes place in the green light. The wavelength of green light is least effective in photosynthesis because plants themselves are green due to the pigment Chlorophyll.

Why is red light most effective in photosynthesis?

Certain red and blue wavelengths of light are the most effective in photosynthesis because they have exactly the right amount of energy to energize, or excite, chlorophyll electrons and boost them out of their orbits to a higher energy level.

Is red or blue light better for photosynthesis?

Trees and plants are green because of a green pigment called chlorophyll. This pigment absorbs red light the best, and converts the light into energy that it uses for metabolism. … However, the pigment doesn’t strongly absorb blue or green light, so plants can’t use this energy for photosynthesis.

How do different colored lights affect photosynthesis?

Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn’t).

Why does blue light work best for photosynthesis?

BLUE LIGHT AND PLANT GROWTH In addition, blue light regulates the opening of stomata, which are the tiny openings on leaves that control both water loss and the uptake of carbon dioxide. Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis.

Why do plants absorb red and blue light the best?

BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth. Blue light has a wavelength that is shorter in the visible spectrum as compared to red light and has a higher energy.

In which light photosynthesis takes place faster?

Explanation: As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After White, We Have Violet Light Where Photosynthesis Occur To A Higher Extent as It Has The Shortest Wavelength Hence Has The Max Energy.

Which color of light is most effective in photosynthesis?

green lightThe majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.

Which light range is least effective in photosynthesis?

green lightThe green light is considered to be the least efficient wavelength for photosynthesis. During photosynthesis, if the plants are exposed to green wavelength, the rate at which the photosynthesis takes place will be the least. This is due to the presence of a green pigment known as chlorophyll.

Why is green light the worst light for photosynthesis?

Plants react differently to different colors of light. … Regardless of whether the color of the light is red or purple the plant will absorb some amount of energy from the light it is receiving. Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.

In which light rate of photosynthesis is maximum?

red lightMaximum photosynthesis occurs in red light. Light is absorbed by photosystem II that is membrane-bound. It absorbs infrared and red light. On the other hand, blue light is absorbed by chlorophyll and carotenoids but some carotenoids are not found in chloroplasts.
