Carotenoids are the dominant pigment in autumn ..
The light-independant reactions of photosynthesis occur in the stroma of the chloroplast and involve the conversion of carbon dioxide and other compounds into glucose. The light-independent reactions can be split into three stages, these are carbon fixation, the reduction reactions and finally the regeneration of ribulose bisphosphate. Collectively these stages are known as the Calvin Cycle.
There is another photosynthetic pigment called carotenoid in plants. The carotenoids also absorb light energy but they pass it to the chlorophyll molecules. Chlorophylls are blue–green (chlorophyll–a) or green (chlorophyll– b) in color whereas carotenoids are orange (carotenes) or yellow (xanthophyll). Chlorophyll is highly sensitive to light, but too much light may destroy it.
Photosynthesis: Pigments and absorption spectra
It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.

Which is the main light-absorbing pigment for photosynthesis?
A limiting factor is a factor that controls a process. Light intensity, temperature and carbon dioxide concentration are all factors which can control the rate of photosynthesis. Usually, only one of these factors will be the limiting factor in a plant at a certain time. This is the factor which is the furthest from its optimum level at a particular point in time. If we change the limiting factor the rate of photosynthesis will change but changes to the other factors will have no effect on the rate. If the levels of the limiting factor increase so that this factor is no longer the furthest from its optimum level, the limiting factor will change to the factor which is at that point in time, the furthest from its optimum level. For example, at night the limiting factor is likely to be the light intensity as this will be the furthest from its optimum level. During the day, the limiting factor is likely to switch to the temperature or the carbon dioxide concentration as the light intensity increases.

The occurrence of photosynthesis is very important to us as humans, because it provides us with the oxygen we need to breathe and plants are at the bottom of every food-chain and so without them, I would collapse....
Which is the main light-absorbing pigment for photosynthesis
Compare the results with the typical Rf values in Table 1, we can
found that all of the pigments have been identified: pigment one is
Carotene; pigment two is phaeophytin; pigment three is xanthophyll;
pigment four is chlorophyll a and pigment five is chlorophyll b.

As we can see, there is a close relationship between the action spectrum and absorption spectrum of photosynthesis. There are many different types of photosynthetic pigments which will absorb light best at different wavelengths. However the most abundant photosynthetic pigment in plants is chlorophyll and therefore the rate of photosynthesis will be the greatest at wavelengths of light best absorbed by chlorophyll (400nm-525nm corresponding to violet-blue light). Very little light is absorbed by chlorophyll at wavelengths of light between 525nm and 625 (green-yellow light) so the rate of photosynthesis will be the least within this range. However, there are other pigments that are able to absorb green-yellow light such as carotene. Even though these are present in small amounts they allow a low rate of photosynthesis to occur at wavelengths of light that chlorophyll cannot absorb.
