Can you tell from these absorption spectra whether red light is effective in driving photosynthesis?

One cannot tell from this graph, but because chlorophyll adoes absorb red light, we can predict that it would be effective in driving photosynthesis.

Do plants need the color of the sunlight to make food?
No. Different chlorophylls (A and B) and accessory pigments (e.g. carotenes, phycobiliproteins) have different absorption spectra. The combination of different spectra determine the colors that the plant uses to perform photosynthesis. A regular green plant will use mostly red and blue-violet light to drive photosynthesis. Green light is mostly reflected and not used.
What is the pigment responsible for photoperiodism?
Action spectra and photoreversibility experiments show that phytochrome is the pigment that receives the red light. Red light is the most effective color in interrupting the night-time portion of the photoperiod.
1 State an advantage having more than one type of photosynthetic pigment gives a plant?
pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra, the absorption pattern of a given pigment. the Light Dependent Processes (Light Reactions) light strikes chlorophyll a in such a way as to excite electrons to a higher energy state. BTW this is a yahoo answers response so give the other person credit. :)
What is definition of protein profiling?
Protein profiling is a process that lets individuals quickly discover the differences in the spectra of protein samples from minute sample sizes. Once discovered, a large sample can be used to find and purify with other arrays.
What sensory neuron respoand to green light?
photoreceptors
How absorption spectra can be used in the identification of unknowns?
Each substance has known specific maximum of absorption. Comparing spectra substances can be identified.
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis Why are they different?
The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
How Many types of Infrared Spectra?
There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.
What is the absorption spectra of phloroglucinol?
540 nm
What is extinction spectra?
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.

Which type of spectrum do most stars have?
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.
