Is chlorophyll necessary for photosynthesis?

Question

this is a biology pproject and we need to find out how to test whether chlorophyll is needed for phtosynthesis. Thanks!

Answer 1

Definitely, chlorophyll is necessary for photosynthesis. Chlorophyll functions to absorb light and transfer that light energy by resonance energy transfer to a specific chlorophyll pair in the reaction center of the photosystems.
There is a simple experiment that can show how chlorophyll is needed for photosynthesis. Check out this wiki page:

Answer 2

While chlorophyll is by far the most popular pigment for use in photosynthesis, the process is possible without it. A relatively small number of types of microorganisms (mostly archaea) complete photosynthesis with other green or violet pigments.

However, this may be different from the question you are trying to test experimentally, which seems to be "Can a plant that uses chlorophyll for photosynthesis complete photosynthesis without chlorophyll?" This is difficult to figure out. If you put a plant in the dark, it won't grow because it can't conduct photosynthesis, and it will become very pale due to not having chlorophyll. However, this isn't a controlled experiment. We didn't take away the plant's chlorophyll; we took away the light, which is also needed for photosynthesis.

Your best bet is to show that there is some photosynthetic organism that doesn't use chlorophyll at all. You'll need to show that such an organism is not green, but still produces energy through photosynthesis.

Answer 3

yes it is very essential for the process of photosynthesis to ake place.

Carotenoids and chlorophyll b absorb some of the energy in the green wavelength. Why not so much in the orange and yellow wavelengths? Both chlorophylls also absorb in the orange-red end of the spectrum (with longer wavelengths and lower energy). The origins of photosynthetic organisms in the sea may account for this. Shorter wavelengths (with more energy) do not penetrate much below 5 meters deep in sea water. The ability to absorb some energy from the longer (hence more penetrating) wavelengths might have been an advantage to early photosynthetic algae that were not able to be in the upper (photic) zone of the sea all the time.

look. no arguments the answer is definately yes



The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) or the membrane infoldings found in photosynthetic prokaryotes such as cyanobacteria and prochlorobacteria.

Answer 4

chlorophyll is like the green plant's main photosynthetic pigments. in its failure, however, accessory pigments, of which carotenoids form a big component of, kicks in to harvest light energy. this is sufficient to maintain basal metabolism in many plants.

i am curious what method you are doing to use to remove chlorophyll. more likely than not, you will also accidentally remove the accessory pigments, and conclude that photosynthesis cannot occur. i advise you to be careful about this.

im not giving too much thought into this, but you could consult the absorption spectra of chlorophyll a/b and filter out these wavelengths in the light that you shine. that way you keep the chlorophyll in there, but make sure they dont work.

Answer 5

Chlorophyll Is

Answer 6

yes, it is necessary for photosynthesis.there is a simple way to prove that: chlorophyll (PSI & II) is activated by light , and photosynthesis starts (the plant is growing).if u put a young plant in darkness for some days , and follow its height for example for these few days, u will realize that the plant is not growing or that it is growing slowly for the first 1-2 days.In this case, the plant is not growing because photosynthesis is not taking place.
I think this is a very simple test u can do.I hope I was helpful.
good luck!

Answer 7

the outcomes are sparkling: without chlorophyll you will have not any photosynthesis. without photosynthesis, the plant dies of starvation. variety of like in case you swallowed foodstuff, yet have been unable to interrupt in all the way down to get entry to the foodstuff.

Answer 8

Nope. Some bacteria use a different pigment for the same purpose.

Answer 9

If you use something to destroy the chrlorphyll, is the plant still able to survive?
