Results for the best conditions for plants to grow.

We are investigating about the colour of light affecting photosynthesis.

Results ( in acsending order )

The colour which makes the plant produce the most oxygen :
1) blue
2) red
3) magenta
4) normal light
5) green light

Our opinion : The results shown that colours indeed affect the rate of photosynthesis and the colour is a factor which keeps the plant alive.

Further explanation : There is a obvious relationship between the amount of oxygen produce and the colour of the light. The amount of oxygen increases as the colour changes. The green light causes the oxygen level to stay at a constant level even after quite some time. So from the result which the green light produced, I can conclude that green light is relected by the plant and doesnt help the plant in photosynthesizing. I can conclude that as before the experiment, our group came out with a theory which is whatever that appears what is appear to be is relecting the colour it appears to be.

Better theory : The other four colour such as white light ( normal light ) , magenta , red and blue shown that it enables and help a plant in photosyntesizing as the amount of oxygen in the water remain inconsistent.From the result, I can conclude that the four colour allow plants to photosynthesize.

My findings : There were certain errors in our experiment such as the amount of oxygen at the beggining in the water. We guess we did not have the equipment to remove the amount of oxygen from the water.The effects of the amount of oxygen in the water could affect the make the amount of oxygen produced by the plant inaccurate.The second reason is the amount of leaves on the hydrilla. For a more accurate result the amount of leaves on the hydrilla must be the same.

Better theory : The experiment could have been better if we were much more particular about the amount of oxygen in the water and the amount of leaves on hydrilla. After checking throught the above stated the results definitly will become even more accurate then before.

Our opinion : The colour of the light in green houses which houses plants.

Conclusion :

My hypothesis was confirmed. I can conclude this as I seen many websites which also has the same results as mine and i even checked yahoo to be even more confirmed.

Overall : My results generalises that colours indeed affect the rate of photosynthesis.
