## Effects of different colors of light on the photosynthesis rate.

### Factors that affect the rate of photosynthesis

Blue carries a lot of energy and is highly absorbed so the level of
photosynthetic rate is high, were as green carries quite a bit of
energy but isn't absorbed at all so the level of photosynthetic rate
is low and red carries little energy but I highly absorbed all these
facts match with my prediction and my results.

### The Effects of Different Light Colors on Photosynthetic Rate

Instead of counting o2 bubbles per min which to
me is inaccurate as every o2 bubble has a different volume and the
accuracy is down to your observation so the likelihood of human error
is very high instead I would measure the volume of o2 given off this
would be far more accurate.

Conclusion-

I can see from my results that white light produced the highest
photosynthetic rate at an average of 382 02 bubbles per min and green
the lowest at an average of 21.3 o2 bubbles per min.

## and their Rate of Photosynthesis ..

experiment with the surrounding temperature at 30 degrees then we may
have found that the rate of photosynthesis would have been very low,
or even that photosynthesis within the pond weed was non existent.

## Measuring the rate of photosynthesis - Science and …

Effectively this shows
that if more of these limiting factors can be used by a larger sample
compared to a smaller sample, then the rate or amount at which the
products of photosynthesis are given off will be at a higher level
too.

## What is the effect on the rate of photosynthesis of ..

The maximum volume of inlet air that can be processed in a compressor (as measured in cubic feet or cubic meters per minute) is similar at any inlet pressure. To deliver the same amount of air (measured in Pounds, Tons, Kilograms, Standard Cubic Feet, Normal Cubic Meters, etc.) when operating at high elevations, a compressor must process greater physical volumes of inlet air than would be required if the compressor were being operated near sea level (about 3.4% more for each 1000 feet or 1.1% more for each 100 meters).

## What limits the rate of photosynthesis

Explanations

Reason 1

When the green plant is provided with a higher concentration of CO2 in
the environment it is photosynthesising in, the rate of photosynthesis
conducted by the plant will be higher - the availability of one of the
limiting factors was higher.

Results obtained from experiment : "Investigating if light intensity
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.

## Light wavelength effect on the photosynthetic rate of ..

Our hypothesis that an increase in carbon dioxide concentrations leads to an increase in the rate of photosynthesis is supported by our experiments’ results.
