What is photosynthesis?

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Robert Emerson discovered two light reactions by testing plant productivity using different wavelengths of light. With the red alone, the light reactions were suppressed. When blue and red were combined, the output was much more substantial.

Who else did our experiment?
After researching previous experiments done on this topic, I found a similar experiment done by three scientists in Colorado in 2003. These scientists used three different colors to our two, red, blue, and green. They were also testing to see which of these lights would allow plants to photosynthesize the fastest. 
The way we did our experiment is by placing the Cabomba Plants in a beaker with a test tube on the top and place it in a box. Inside the box, we had set a light source up with four different colours: Blue, Red, Green and White / Natural light.

Conclusion

Practical Applications

Cabomba plant is a common water plant that is placed in aquariums . With our research , we  advise fish tank owners to place their aquariums under white lights as this allows the water plant to photosynthesis and produced more oxygen. This will allow the fish tank owners to be less reliant on their oxygen pumps.

Our research is also able to benefit the environment by allowing plants to photosynthesis more. This will benefit us as the plants will produce more oxygen . People who grow plants will also benefit from our results. This is because indoor farming requires the environment to self -sustainable . With our results , we hope to advise indoor farmers to use white light to create a more sustainable environment for their plants  .

Areas for further study
We can investigate whether we obtained the same results for different plants , this includes different types of water plants and land plantsIn addition , we could bring our investigations to a higher level . We could investigate how do we install system equipped with lights to allow the plants to produce more oxygen for the different environments they are placed in . We may also design aquariums eco­ systems with Cabomba plants to create a self sustaining eco­system without the need for oxygen fliters .


Ending Paragraph
In total , we have done 3 sets of experimentation. Our results differ from our hypothesis , this may due to :
1.All the colours of the rainbow have different wavelengths. For example, violet has short wavelengths, while red has long wavelengths. Visible light appears as white light because it is a mixture of all the colours. Also, chlorophyll is the principal pigment involved in photosynthesis. 2. Chlorophyll absorbs all the different coloured wavelengths, but leaves green as the colour it reflects and as the colour we see. Therefore, white light is best to grow plants under because green light doesn't do much of anything for photosynthesis. 3. The wavelength in which chlorophyll works best is in the red and blue range, and therefore does not absorb the green wavelength which is why leaves appear green.
Through our experiment we discovered that there are different rates of photosynthesis that occur in different light conditions with the answer to our question we also discovered that our hypothesis was wrong.
We initially thought that the plant grows best under red light. But after our experiment, we realised that the white / natural light grows best instead.
Areas to improve : We could keep the rest of the Cabomba plants in sunlight as over the time the a.Cabomba Plants slowly died out. b. We need to repeat the experiment more times to ensure reliable results c. We have to make sure each time we redo the experiment, we record data at the same time interval d. We must also make more efforts to make sure we cut out the same amount of plant for each set-up
Our research is also able to benefit the environment by allowing plants to photosynthesis more. 

This will benefit us as the plants will produce more oxygen .
People who grow plants will also benefit from our results. This is because indoor farming requires the environment to self ­sustainable . With our results , we hope to advise indoor farmers to use white light to create a more sustainable environment for their plants . (West Bridge Farms pg 1)
With our research , we advise fish tank owners to place their aquariums under white lights as this allows the water plant to photosynthesis and produced more oxygen.
