Boilogy question. Need experiment to show that chlorophyll absorbs sunlight.?

Question

Describe an experiment to test how chlorophyll absorbs certian wavelengths of sunlight, and yet doesn't absorb the bright green light.
Just an easy one would do.
I just can't think of one though.

...chlorophyll doesn't absorb green light, right?

Answer 1

Take a living plant one with a big leaf, place a piece of clear tape over it and then expose it to light. Paint the tape green.
see what happens. I think you shoudl do some work, no??

Answer 2

Hm..this is the procedure
1.take few leaves in a mortar and add a pinch of Magnesium.
2.Crush the leaves with little amount of any organic solvent like acetone,ether,etc.Dont pour the entire solvent at once.add little by little.
3.crush well
4.filter through a muslin cloth or a filter paper.
5.collect the green coloured solvent in a test tube.
6.Now take a colorimetre or a spectrophotometer
7.take a cuvette(small test tube) and pour some distilled water.
8.adjust the OD of the colorimeter to zero with the help of the distilled water.
9.Now take the filtered green solvent in a new clean cuvette and take OD readings at different wavelenghts.
8.Plot the OD reading against wavelenghts to obtain an absorption curve.
9.two peaks are seen in the graph.
10.these corresponds to the wavelenghts that the chlorophyll absorbs.

Answer 3

Maybe you can extract chlorophyl from plant material and do the uv-vis spectrum of the solution vs that of the same solvent without the chlorophyl?
