参考答案:
The action spectrum shows the rate of photosynthesis at different light intensities (of the visible spectrum).
The absorption spectrum shows the amount of light energy absorbed by chlorophyll at each light intensity.
Not all wavelengths (of light) are absorbed by chlorophyll.
The energy absorbed by chlorophyll is used to excite electrons.
Excited electrons produce ATP/chemical energy used by photosynthesis.
Geen light has the lowest absorption and lowest rate of photosynthesis/violet light has the
highest absorption and highest rate of photosynthesis.
