What is the relationship between light wavelength and photosynthetic rate?
Some light wavelengths improve the rate of photosynthesis. The best colors for photosynthesis are blue and red while yellow is the worst.
Engelmann's investigation to determine the effective wavelengths of light in photosynthesis depended on a photosynthetic alga's?
release of Oxygen
Can plants really go through photosynthesis as long as the spectrum part of the artificial light has wavelengths that the chlorophyll can grab?
yes
Engelmann's experiment determined which wavelengths of light are most effective at causing photosynthesis In other words Engelmann measured?
blue and red.
Plants are exposed to red blue and yellow wavelengths of light and the amount of oxygen produced during photosynthesis What can you sugest for a control group?
Plants exposed to white light?
What is the color of light that is the least useful to plans during photosynthesis?
red and blue light is most useful. But others are not.
What wavelengths of light are absorbed for photosynthesis?
380-500 and 575-750
Which light has the least affect on photosynthesis?
Green light has the least affect on photosynthesis.
Can heat be used as an energy source when there is no light for plant growth?
No. Certain wavelengths of light are needed for photosynthesis. The appropriate wavelengths are not present in purely thermal energy.
Are wavelengths used in photosynthesis primarily infrared and ultraviolet?
No, the wavelengths are between visible light(around 400-600nm i guess)with the exception of the wavelength of green light.
Is it true that the wavelengths of light most effective in photosynthesis are those in the green part of the visible spectrum?
No
What particular wavelenghts photosynthesis depends on?
Photosynthesis only depends on visible light so therefore the wavelengths range from 390 to 750 nm.
What is the relationship between light wavelength and photosynthetic rate?
Some light wavelengths improve the rate of photosynthesis. The best colors for photosynthesis are blue and red while yellow is the worst.
What wavelengths of visible light can plants use as a source of energy?
Most of the visible light spectrum except green wavelengths is absorbed by the chlorophyll molecule and is usable in photosynthesis as a source of energy for plants.
Engelmann's investigation to determine the effective wavelengths of light in photosynthesis depended on a photosynthetic alga's?
release of Oxygen
Are some wavelengths of light more important than others?
There are only certain wavelengths that can be accepted and absorbed by chlorophyll molecules. The rest are instead reflected - the colors that you can see. Without those wavelengths, you do not have photosynthesis.
Do plants grow taller in green light or white light?
All the colours of the rainbow have different wavelengths. For example, violet has short wavelengths, while red has long wavelengths. Visible light appears as white light because it is a mixture of all the colours. Also, chlorophyll is the principal pigment involved in photosynthesis. Chlorophyll absorbs all the different coloured wavelengths, but leaves green as the colour it reflects and as the colour we see.Therefore, white light is best to grow plants under because green light doesn't do much of anything for photosynthesis.
