Limiting factors are:

* Carbon Dioxide

* Temperature

* Amount of water

* Light Intensity

If we run out of Carbon dioxide, water or light photosynthesis cannot
take place.

 Method I will place the piece of Elodea Canadensis and place it in the syringe.

This is an often misunderstood aspect of aquarium plant keeping.
There is so much anecdotal information that is out of date with more current aquarium/plant biochemistry information. Not only do plants need many of the minerals found in GH, but, just as important, potentially dangerous upward pH swings can occur if your GH is much below 50 ppm during peak plant photosynthesis.
For example, I observed a pH of 6.8 in the morning and then a pH of 7.4 in the afternoon in a tank where GH was low or almost non-existent.

Plants Profile for Elodea canadensis (Canadian waterweed)

There was trouble collecting the proper amount of water and the correct size of the Elodea plants.

The Effects of pH Levels and Phosphorous on the Photosynthesis Process of Aquatic PlantsStudy the coniferous spruce tree (Picea glauca as the species of choice) by measuring its lateral and sub-lateral branch angles in order to see how it collects sunlight from various angles on its south-facing side.

The reactions of photosynthesis take place in two main stages: a)

The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

We had learned from the experiment that an Elodea plant in water and pH of 11 solution will grow the fastest under the same conditions of a plant in a pH of 7 and 3.

Demonstrating Oxygen Evolution During Photosynthesis …

Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).

Conclusion

I have realised in this experiment that without the products of
photosynthesis all living organisms would die, including plants as
eventually the limiting factors would run out such as carbon dioxide.

Nutrition, digestion and excretion

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....
