Would you expect a plant to be able to photosynthesize if exposed to only green light wavelengths?
What would happen if plants are exposed to only green light? Plants appear green because they absorb all wavelengths of the spectrum except green; If plants were only exposed to green light the rate photosynthesis would decrease.
What would happen to a plant place under green light only?
If a plant is given only green light, no photosynthesis will occur. Green light is not absorbed by the photosynthetic pigments as it is reflected back as such.
Do plants have to be green to photosynthesize?
At low light levels, green leaves are most efficient at photosynthesis. On a sunny day, however, there is essentially no difference between red and green leaves’ ability to trap the sun’s energy. I have noticed the presence of red in the new leaves of many Bay Area plants as well as in numerous tropical species.
Can a plant survive with only green light?
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. Sometimes one may hear that plants don’t use green light for photosynthesis, they reflect it. However, this is only partly true.
Why does photosynthesis occur most slowly under green light?
No light gets absorbed by chlorophyll means the plant can’t do photosynthesis. Answer 3: Trees and plants are green because of a green pigment called chlorophyll. However, the pigment doesn’t strongly absorb blue or green light, so plants can’t use this energy for photosynthesis.
Why is green best for photosynthesis?
Cyanobacteria and later plants, have oxygen as the waste product of photosynthesis. Thus slowly Earth became oxygenized. This Great Oxygenation Event wiped out most of the anaerobic organisms including the purple bacteria. So plants are green because chlorophyll is more suited for a blue or a red sun.
Can photosynthesis occur in green light or red light?
Since, the green light is reflected by chlorophyll, plants appear green to us. Photosynthesis can take place in both Red and Blue light, but its rate is maximum in Red light.
Can plants photosynthesize without chlorophyll?
If plants require chlorophyll to produce energy from sunlight, it’s logical to wonder if photosynthesis without chlorophyll can occur. The answer is yes. Other photopigments can also utilize photosynthesis to convert the sun’s energy. In fact, even plants that are green have these other pigments.
