Factors affecting the rate of photosynthesis 1

Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.

In practice, any one of these factors could limit the rate of photosynthesis.

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.

So how can these factors have an effect on the rate of photosynthesis? Lets start off with the light intensity. When the light intensity is poor, there is a shortage of ATP and NADPH, as these are products from the light dependent reactions. Without these products the light independent reactions can't occur as glycerate 3-phosphate cannot be reduced. Therefore a shortage of these products will limit the rate of photosynthesis. When the carbon dioxide concentration is low, the amount of glycerate 3-phosphate produced is limited as carbon dioxide is needed for its production and therefore the rate of photosynthesis is affected. Finally, many enzymes are involved during the process of photosynthesis. At low temperatures these enzymes work slower. At high temperatures the enzymes no longer work effectively. This affects the rate of the reactions in the Calvin cycle and therefore the rate of photosynthesis will be affected.

#42 Effect of Temperature on the Rate of Photosynthesis

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...

This is the rate of photosynthesis at that particular ..

The rate of photosynthesis is also affected by limiting factors.
How can this be applied in the real world?

Factors affecting the rate of photosynthesis.

variable affects the rate of photosynthesis

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....

The graph produced from this experiment isn’t very ..

Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.

how temperature affects photosynthesis

Things to remember!
When there is no light, photosynthesis can't occur since light is the activation energy needed for plants to convert carbon dioxide and water to glucose and oxygen
When there is no light, the plants would use up oxygen therefore emitting carbon dioxide bubbles instead.
The plants should be given a couple minutes to start initiating the process of photosynthesis before you start timing.
The Scenario:
Reona and Michael have been growing aquatic plants for a while, specifically Elodeas which is a type of pond weed.
