The question is in regard to leafs, as my resident teenager just had the same homework. It is poorly worded, as it should be asking, "Why does a leaf exhibit a low oxygen flow when illuminated only by green light" ...or something along those lines.
In simple terms, chlorophyll feeds the plant by converting light and CO2 into 'food' and O2. A lack of oxygen means that this chemical reaction isn't occurring. Why? A lack of light. The chlorophyll is green because it primarily reflects green and yellow light, meaning that it absorbs (and uses) the reds and blues. Shining a green light on a plant is almost the same as not shining any light on it.

∙ 12y agoBecause green plants reflect green light (that is why the look green) and therefore can not use its energy.

What would happen if the guard cells are closer together?
The stomata would be narrower, thus osmosis would occur less, thus photosynthesis would be less. The stomatal pore will become narrower. Gaseous exchange to and fro stomata will be reduced. This will affect the rate of photosynthesis in green plants.
What are potential benefits of an increased rate of photosynthesis?
Photosynthesis is the single most important function in all of living things. An increased rate of photosynthesis will allow the process to be not as effective.
What are the two stages in photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
What describes a hypothesis?
State the changed and observed variable. E.g.: the higher the intensity of the light, the higher the rate of photosynthesis. Heehee I'm pretty certain I'm correct. And I'm 12! Haha
What happens to a plant if rate of respiration becomes more than the rate of photosynthesis?
supposedly if plants carried out photosynthesis and respiration at the same rate, then the plant would have no excess sugars (energy)to last them the night... remembering that photosynthesis would only work in daylight hours. Thus, the plant would starve to death basically every night and there would be no life on the earth. All the plant eaters would die making the meat eaters die with them and then there would be no CO2, which is required in photosynthesis... yeah it would be chaotic. i would do a little more research if i were you to make sure im right :)
What colour of light would drive photosynthesis at the highest rate red blue or green?
blue light
How does the color of light affect the rate of photosynthesis?
If white light is a mixture of several wavelengths of colors and the chlorophyll in green leaves absorb energies from all visible light except green, then exposing white light to a green plants will result in the fastest rate of photosynthesis, followed by blue or red.
How does light intensity and the rate of photosynthesis relate to the position of the sun?
Light intensity and the rate of photosynthesis relate to the position of the sun in a few ways. The higher the sun the faster the rate of photosynthesis.
How does light intensity affect the rate of photosynthesis?
Higher light intensity increases the rate of photosynthesis and vice versa.more intense light means more energy in the light, so the chloroplasts get more energy from light, making photosynthesis go faster
What effect does the amount of light have on photosynthesis?
It increases the rate of photosynthesis.
What is the relationship between light intensity and photosynthetic rate?
The relationship between light intensity and photosynthetic rate is that if the intensity of the light is high then the rate of photosynthesis will increase. However the rate of photosynthesis will only increase to an extent after intensity of light reaches a certain point photosynthesis rate will stay still.
What color produces the lowest rate of photosynthesis?
green
How does changing the light intensity effect photosynthesis and why?
By changing the light intensity the rate of photosynthesis will either increase or decrease because it is one of the factors that affects photosynthesis. If you increase the light intensity the rate increases but if you decrease the light intensity the rate decreases.
Does the rate of photosynthesis depend on the duration of light?
Low light intensity lowers the rate of photosynthesis, Normal sunlight is good for a normal rate of photosynthesis, Very high intensity bleaches (destruction) the chlorophyll
Which color of light would you expect to produce the LOWEST rate of photosynthesis?
Green. Only because green is the color appearance and sunlight is only absorbed by the color showing.
What mostly happens to the rate of photosynthesis as white light levels are decreased?
It decreases. Photosynthesis depends on the availability of light.
What is the relationship between an increase in light intensity and photosynthetic rate in tomato leaves?
As light intensity increases then the rate of photosynthesis increases until a point is reached when the rate levels off. Beyond this point is called the light saturation point of photosynthesis.
