Other students who did the same experiment had results that also supported that blue light was not responsible for the rate of photosynthesis. Experiments Warsh et al. 2001, Bahramzadeh et al. 2001, and Whorley and Weaver. 2002 all showed that red had much higher rates of photosynthesis than blue, but these experiments had fewer trials or shorter trials. Lots of other students also used white light as a controlled variable; this would have been a good thing to put into our experiment to give it some comparison.

The effect of temperature on photosynthesis ..

Oxygen bubbles are given off by the plant in response to photosynthesis.
This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants.
Investigate The Influence Of Carbon Dioxide On The Rate Of Photosynthesis Biology – Leaving Cert Experiments.
In this practical experiment, the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of Cabomba pondweed.
When the temperature rises the rate of photosynthesis rises also.

You can show by experiment the rate of photosynthesis is proportional to the light intensity where it is the limiting factor.



If placed in a suitable nutrient environment, cells and tissues of many organisms are ableto reproduce and form new plants or animals. Now, we will deal with vegetable tissues,whose culture is simpler than that of animal cellules and tissues. It is necessary toprepare a nutritive and sterilized culture medium for the piece of plant tissue. Keep theculture in the suitable conditions of light and temperature and which vary from plant toplant. Over many days, you will observe the growth of a callus or roots or shoots. In thisway you can obtain even whole plants (cloning). These experiments show that special cellskeep all the information necessary to generate the whole plant.
As we have mentioned, it is necessary avoid bacteria and moulds in the cultures. For thisyou will need sterilize tools, vials, tubes, and nutrient medium. Place each in anautoclave for a ten minutes or, lacking an autoclave, a pressure cooker. The tissues aswell have to be free from microorganisms and they have to be sterilized with bleach (40%solution for 15 min) or with alcohol.
The transfer of the tissues into the test tubes has to be made in aseptic conditions,using a sterile box. Lacking that, make your first trials in a quiet place, as devoid ofwind and dust as possible. The culture medium should contain water, vitamins (particularlythose of the B-complex. For this, use yeast extract), sugars, mineral salts. To enrich thewater with mineral salts, boil some water with a handful of soil, then let settle andfilter it. Usually, people also insert 0.5-0.8% of agar-agar to "solidify" themedium. As culture medium, coconut milk has been used. It contains mineral salts, sugars,vitamins and growth hormones.
1 - For yours first tests of micropropagation, use strawberries tissues.
2 - If this simple experiment interests you, you can continue on the way of the invitro culture of vegetable tissues. In fact you can propagate a lot of plants in thisway. Plants easy to culture are the following: tomato, potato, strawberry, chrysanthemum,geranium, sunflower, tobacco, carrot and onion. You can use tissues obtained from seeds,such as the embryo, but you can use also tissues taken from adult plants, such as tissuesof roots, stems, apical buds, shoots, leaves, even single cells. Each plant and tissue hasits own needs. They are different from each other. You can try the influence of thevegetable hormones, special nutrients, etc.
This field is very broad and complex so, if you are interested in continuing with theseexperiments, you can buy special books and you should build a sterile box.

The effect of temperature on photosynthesis: ..

Organic compounds are formed using C02 and the chemical energy stored in ATP and NADPH.
How does temperature effect the rate of photosynthesis?
Importance of this experiment
The reason this experiment is important is because when knowing how temperature affects the rate of photosynthesis environmentalist will be able to plant trees in places where the trees can produce the most sugar creating produce and also if a trees is needed to grow somewhere else knowing how temperature affects the rate of photosynthesis helps one figure out if a certain plant can be grown at a different environment but have the same rate of making sugars.
Price of experiment
The price of each tree is about $2.00 per pack of seed.

to show the effect of temperature on the ..

Also, the at very cold temperatures and very hot temperatures the rate of photosynthesis did not occur at all, but in temperature close to 20 degrees Celsius (10,30,40 Celsius) photosynthesis did occur but at a slower rate.
Conclusion
Since we put the plant in different environments different degrees (O,10,20,30,40,and 50 degrees Celsius) the temperatures rose until it reached 20 degrees Celsius then after it hit its climax the amount of oxygen gradually decreased.
The results from the simulation were that at 20 degrees Celsius the amount of oxygen (41.1 mL/h) from the plant increased dramatically showing that the rate of photosynthesis was faster when the plant's environment temperature reached 20 degrees Celsius.

effects the rate of photosynthesis in an aquatic plant."

As mentioned previously, the results I have obtained from the
experiment will be of measured in 5 intervals, ranging from 0cm
-100cm, 1 repeat reading taken as well as an original reading & an
average of the 2 results calculated.
