I am doing an experiment and need to know if the distance that a plant is placed from a light source affects the amount of oxygen it produces.

of course yes...because the distance has a invers proportionality with the quantity of light to the plant ;)
consider u being at a distance of 100 m from school and at 10km from school (no cheating with bus pls:P)...if u walked that distance...on which one would u have consumed more energy?:)
not a good example..but still:)

Assuming you are not at saturating levels of light (i.e. above that which allows maximum rates of photosynthesis) the distance from the light source will have a effect of photosynthesis based on the number of photons of the correct energy falling on the leaf surface. This relationship will be defined by the the square of the distance from the light source. Thus, if you are at a distance of 2 meters in the first test (2x2=4) and 4 meters in the second test (4x4=16), the light intensity and the rate of photosynthesis will be approximately one fourth as much (4/16=0.25). Some plants perform better in high light and some better in lower light, so the relationship between intensity and rates of PS are not exact, but this is a good first approximation.

i do no longer think of photon's lose power with distance yet geometrically conversing they must cover ever increasing factors because of the fact the sunshine source is moved far flung from the image voltaic cellular. As such the quantity of light power falling on the (fixed length) image voltaic cellular decreases. And if the area is sufficiently super so as that the sunshine source would be seen a "factor source" then the INVERSE sq. regulation holds. it fairly is, the sunshine intensity on the fixed section image voltaic cellular will decrease because of the fact the inverse sq. of the separation distance from source to cellular.

Yes, u c, since suinlight cant reach the other planets , or the heat over whelms them, they cannot produce plants, and oxygen comes from plants.

Hi. Is that your experiment? I think you will find that brightness has an effect and duration also has an effect.
