Why doesn't the action spectrum for photosynthesis exactly match the absorption spectrum of chlorophyll a?
The action spectrum for photosynthesis doesn't exactly match the absorption spectrum of chlorophyll a because other pigments, like chlorophyll b and carotenoids, also play a role in capturing light energy for photosynthesis. These additional pigments have absorption peaks at different wavelengths, contributing to the overall light absorption by the plant. As a result, the combined absorption spectra of all pigments involved in photosynthesis do not perfectly align with the action spectrum.
What else can I help you with?
What is the taking in of light energy by an object?
the taking in is a misinterpretation since there is no such thing as "taking in" however what you are thinking is light not bouncing off. and that is exactly what happens, some things absorb light while other do not this depend on the chemical properties of the material. while other simply refelct it or allow it to travel through.
What on the electromagnetic spectrum has the highest frequency?
The visible spectrum : - red, orange, yellow, green, blue, violet. The blue end of the spectrum has a shorter wavelength, higher frequency and more energy than the red end of the spectrum. Thus violet light has the highest frequency and most energy.
What color is the shortest wavelength?
The shortest visible wavelength is the last color you can see on the blue/violet end of the spectrum. It's not exactly the same for all eyes.
Why is the mixture of all colors of the light spectrum called white light?
If all colors of light are mixed, the light becomes white, hence white light. Most lights used to light buildings are not exactly white since they only contain certain wavelengths of light in the spectrum.
What light intensity would their be no net productivity?
The compensation point is the light intensity at which the rate of photosynthesis exactly matches the rate of respiration, resulting in zero net productivity. Below this threshold, the plant consumes more energy through respiration than it is able to produce through photosynthesis, leading to no net gain in biomass.
Do leaves give food to flowers?
Not exactly food, but the chlorophyll within them absorbs sunlight through photosynthesis, and then provides energy through respiration.
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
Which letter identifies the structure that captures sunlight energy for photosynthesis?
The letter "C" typically identifies the structure that captures sunlight energy for photosynthesis, which is the chloroplast. This organelle contains chlorophyll, a pigment that absorbs light energy used in the photosynthetic process.
What exactly is the function of chlorophyll in the food chain?
Chlorophyll is a green pigment found in plants, algae, and some bacteria that plays a crucial role in photosynthesis, the process by which these organisms convert sunlight into chemical energy. By absorbing light, primarily in the blue and red wavelengths, chlorophyll enables plants to convert carbon dioxide and water into glucose and oxygen. This glucose serves as a primary energy source for plants, which are then consumed by herbivores, forming the foundation of the food chain. Thus, chlorophyll is essential for producing the organic matter that supports life across various ecosystems.
Does sunlight cause photosynthesis?
It doesnt exactly trigger it, but sunlight is needed to complete the process Photosynthesis is powered up by light.It is very essential for photosynthesis
What would happen if plants do not contain chlorophyll?
chlorophyll being green, is absorbing the relatively low energy red light and reflecting the higher energy green. But even this sort of analysis depends on the properties of the incoming light. Chlorophyll would be better in the redder light of some stars and poorer in the bluer light of others.
What are the three overhead absorption rates?
As far as I know there is only an overhead absorption rate and a full absorption rate. The alternative being marginal costing. There are 3 methods of absorption costing. These being Activity, Time and Efficiency but I'm not sure what you are asking exactly.
Is carbon dioxide as a waste describing photosynthesis?
I'm not exactly sure, but I'm almost 100% sure that it's respiration not photosynthesis
Where exactly do you find photosynthesis?
Outside, I think you should go and look outside.
What coler in the visible light spectrum has the lowest frequency?
That would be the last color you can see on the red end of the spectrum. It's not exactly the same at all intensities or for all eyes.
What makes Elodea cells green?
Plants are green because they have a substance called chlorophyll in them. Understanding why chlorophyll is green requires a little biology, chemistry and physics.If we shine white light on chlorophyll, its molecules will absorb certain colors of light. The light that isn't absorbed is reflected, which is what our eyes see.A red apple appears red because the molecule of pigment in the apple's skin absorbs blue light, not red. Thus, we see red. Chlorophyll molecules absorb blue light and some red light. The other colors are reflected resulting in the green color that we associate with plants.Plants get their energy to grow through a process called photosynthesis. Large numbers of chlorophyll molecules acts as the antenna that actually harvest sunlight and start to convert it in to a useful form. Here's where the absorbent properties of the chlorophyll molecule come into play.It turns out that eons of evolutionary design have matched the absorbance of chlorophyll to the actual color of the sunlight that reaches the leaves. Sunlight consists of primarily blue and red light mixed together, which are exactly the colors that chlorophyll molecules like to absorb. Light is a form of energy, so the chlorophyll is able to harvest the sunlight with little waste.3 years ago
Are specific spectrum of electromagnetic radiation the cause for color if true which causes which?
Not exactly. Different colors are different frequencies of light. "Spectrum", on the other hand, refers to an analysis of a mix of wavelengths.
