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.
What else can I help you with?
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 color produces the lowest rate of photosynthesis?
Green light produces the lowest rate of photosynthesis because chlorophyll, the main pigment responsible for photosynthesis, absorbs red and blue light more efficiently than green light. This results in green light being less effective in driving the photosynthetic process.
Which color of light would you expect to produce the LOWEST rate of photosynthesis?
Green light would be expected to produce the lowest rate of photosynthesis as plants primarily absorb red and blue light for photosynthesis, while green light is reflected, making it less effective for driving photosynthetic processes.
What colour of light would drive photosynthesis at the highest rate red blue or green?
Blue light typically drives photosynthesis at the highest rate because chlorophyll, the pigment responsible for capturing light energy for photosynthesis, absorbs blue light most effectively. Red light is also important for photosynthesis but is less efficient than blue light in driving the process. Green light is least effective because chlorophyll reflects rather than absorbs green wavelengths.
What is the relationship between light wavelength and photosynthetic rate?
The relationship between light wavelength and photosynthetic rate is governed by the absorption spectrum of chlorophyll, the pigment responsible for photosynthesis. Chlorophyll absorbs blue and red light most efficiently, while green light is least absorbed. Therefore, light wavelengths in the blue and red spectrum tend to have a greater impact on photosynthetic rate compared to green light.
Does the type of light affect photosynthesis?
Yes, the type of light does affect photosynthesis. Different wavelengths of light can impact the rate of photosynthesis in plants. Blue and red light are most effective for photosynthesis, while green light is less effective because it is reflected rather than absorbed by plants.
What effect does the amount of light have on photosynthesis?
Light intensity directly affects the rate of photosynthesis. As light intensity increases, so does the rate of photosynthesis, up to a certain point where the rate levels off or decreases. Plants require a certain amount of light to carry out photosynthesis efficiently.
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 the color of light affect the rate of photosynthesis and why does light color play a significant role in this process?
The color of light affects the rate of photosynthesis because different pigments in plants absorb different colors of light. Chlorophyll, the main pigment involved in photosynthesis, absorbs red and blue light most effectively. This is why plants appear green, as they reflect green light. Light color plays a significant role in photosynthesis because it determines the amount of energy available for the process. Plants need specific colors of light to efficiently convert light energy into chemical energy through 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 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.
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
How does the distance of light from a plant affect the rate of photosynthesis?
The distance of light from a plant affects the rate of photosynthesis because light is needed for the process to occur. If the light source is too far away, the plant may not receive enough light energy to carry out photosynthesis efficiently, leading to a slower rate of photosynthesis. Conversely, if the light source is too close, it can cause damage to the plant's cells. Therefore, the optimal distance of light from a plant is important for maximizing the rate of photosynthesis.
