Effect of different colors of light on the rate of photosynthesis.

Photosystem I is the light energy complex for the  used in some photosynthetic prokaryotes.

Effects of different colors of light on the photosynthesis rate.

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.

This is called photosynthesis, which means "making through light".

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

I believe this will happen because when the light source is nearer to the plant more of the plants surface area is coming in to contact with the light from the desk lamp therefore more photosynthesis will occur which will mean more oxygen will be produced which will create more bubbles....


The human eye usually perceives light in the wavelength range of ..

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.

Most plants have the highest rate of photosynthesis …

Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.

Another limiting factor is the wavelength of light.

I will do this by placing the Elodea in a test tube with sodium hydrogen carbonate then I will vary the light wavelength (color) using colored filters and count the number of oxygen bubbles given off using a pencil dot technique....

Effects of Blue and Red Light on the Rate of Photosynthesis

Some of these variables are listed below: · Light Wavelength · Carbon Dioxide (sodium hydrogen carbonated) · Temperature · Water All these factors will have to be kept constant except the...

Photosynthesis Experiment Lab Light Intensity ..

I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....

Why the rate of Photosynthesis is higher in red light …

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...

the relationship between wavelength of light and ..

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....
