|
|
Photosynthetic pigments have the same optimum temperature as the enzymes used in photosynthesis.
|
|
|
Plants absorb the same photosynthetic pigments for use in photosynthesis.
|
|
|
Only wavelengths of light absorbed by pigments can be used in photosynthesis.
|
|
|
The amount of energy absorbed by photosynthetic pigments is equal to the activation energy for photosynthesis.
|
Detailed explanation-1: -This is because action spectra measure the best wavelength capable of promoting photosynthesis at a faster rate. In absorption, spectra measure the absorbed wavelength by the pigment at greater efficiency.
Detailed explanation-2: -At which wavelength do they show peaks? Overlapping of action and absorption spectrum indicates that light absorbed is used for carrying on photosynthesis. Peaks for action and absorption spectrum is shown in blue violet and red regions of spectrum. This is true for chlorophyll.
Detailed explanation-3: -Each pigment has a characteristic absorption spectrum describing how it absorbs or reflects different wavelengths of light. Wavelengths absorbed by chlorophyll and other photosynthetic pigments generate electrons to power photosynthesis.
