Increasing the light intensity will boost the speed of photosynthesis

Aim: To see if raising the light intensity increases the rate of photosynthesis.

The Effect of Light Intensity on the Rate of Photosynthesis

However, the light is too intense for most plants to be any closer than 24” of our light source*Raising the light higher above your plants increases the light coverage, but also decreases the light intensity.

Prediction:I predict that raising the light intensity will increase the rate of photosynthesis.

with decreased light the rate of photosynthesis must ..

(The taking place within
the plant will increase)

For example, in terms of when a plant completes the process naturally
(without human interference) it is scientifically known that the
process is greatest at mid-day, when the sun is highest, and from
after this point, when the sun gets lower and less light is available
to the plant, the rate of the process decreases, until nightfall where
no such process takes place.

Hypothesis I predict that the more intense the light, the higher the rate of photosynthesis.



My reasons for believing my results are reliable & accurate are
firstly, they agree with the theory behind the rate of photosynthesis
when light intensity is increased, secondly the result which I gained
compared accurately to my prediction, which was well thought out
before it was made, and finally the results I gained for my final
experiment differed so much to the results of my preliminary procedure
which was very inaccurate.

Aim Our aim is to find out how light intensity affects the rate of photosynthesis.


of light intensity on the rate of photosynthesis ;

Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.

Light Intensity in Plant Growth and Development

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.

As the intensity is increased the rate also increases

My reason for believing this
is that as mentioned previously, light is one of the limiting factors
required for photosynthesis, and by lowering the amount of light
available to the plant, I will be decreasing the rate at which the
process of photosynthesis takes place in the plant.

Factors affecting rate of chemical reaction - …



Prediction

I predict that by varying the light intensity the pond weed is
provided with, that as the light intensity becomes lower, so will the
outcome I will be measuring (the rate of oxygen bubbles given off by
the plant will decrease), and vice versa.

Light, Temperature and Humidity | Ornamental …

I had
enough results to reach a conclusion and my results prove that light
intensity is effects the rate of photosynthesis: the further the light
the slower the rate of photosynthesis.

Plant Energy Transformations-Photosynthesis - …

We compared our results with Anisha's group's results
and also I drew graphs of their group and this also clearly states
that the light intensity affects the rate of photosynthesis.
