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. :)
Why does spinach extract turn red in bright light?
I don't know the source of your "bright light". If it's sunlight, which of course has some UV in it, or if you take the extract into a dark room and shine a "black light" on it, you will see fluorescence. The source of the red color is chlorophyll. When in place in the leaf, the electrons of chlorophyll absorb solar energy. These excited electrons then fall into an electron transport chain that will strip them of the added energy, using that energy to form ATP and NADPH. The red color you see when you illuminate chlorophyll in a spinach extract with UV is the fall of those "excited state electrons" back into their "ground state". In falling, they shed their energy in the form of red light.
Explain why water is essential for the light reaction?
Water is essential for Light DEPENDANT reactions, because the plant needs the hydrogen ions from the H20 to perform photosynthesis.
What molecule is responsible for capturing light energy in a plant?
Light is first captured by the enzyme P680 in photosystem II. Two electrons are absorbed from the incoming light energy and these move P680 to the excited state commonly written as P680*. For more information, look up "Z Scheme" this should clear up more about the entire process of light absorption and transformation into chemical energy in photosynthesis.
What was three steps the hohenzollern's did to build up their state?
In a parliamentary state, the head of government depends on the confidence of the parliamentary majority, and certainly has the right to form coalitions to ensure his policies a majority, but in Germany, the Chancellor depended on the confidence of the Emperor alone, and Wilhelm believed that the Emperor had the right to be informed before his minister's meeting.

What is the Vermont average cost per pupil?
The average cost per pupil in the state of Vermont is $15,925. This is quite a bit higher than the national average of $10,560.
What expands and contracts to change the size of the pupil?
The pupil changes size because of a little organ called the iris. The iris works like a gate or like the shutter on a camera. It is nearly closed when the light is very bright. It is wide open in very little light.
Are amber light bars legal on vehicle without permits?
Generally, no, although the laws may vary by state, and your best advice is to inquire with your state about them before mounting them.
What is a pupilage in law?
pu·pil·age also pu·pil·lage play_w2("P0664800") (pyp-lj) n. The state or period of being a pupil. hm()
State with the most light houses?
The state with the most light houses is Michigan.
Can you light firecrackers in the state of Nebraska before the Fourth of July?
In many states Fire Crackers are legal regardless because they are not deadly.
Which state help produce light in fluorescent light bulbs?
Which state helps produce light in fluorescent lightbulbs?
Can you spot light wild hog in Texas?
Yes you can but since there has been a lot of poaching in the state it is best to let a game warden know before you do it.
Why do elements produce light?
Some elements produce light because of a change in energy state levels. The color of the light is determined by the difference in energy between the excited state and the ground state.
What state helps produce light in fluorescent light?
plasma
Can't pass inspection with Kia Sedona airbag light on?
Depends where you live each state has different rules and states like Florida don't even require an inspection sticker. Ask a local garage before you bring the vehicle in for inspection, if your state requires the air bag light be off to pass you can either have it repaired or remove the bulb before getting the inspection done.
