Elodea pond weed
Cold water from tap
The apparatus was set up as below:
Elodea that was kept well illuminated in a lab was taken for this
Lab: Exploring the Rate of Photosynthesis - The …
Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.
Input - Light intensityis to be varied by increasing and decreasing
the distance from the light source to the plant
Output - The rate of photosynthesisis to be measured by counting the
bubbles of oxygen produced by the plant every two minutes, and
therefore finding the rate of photosynthesis
Control - The amount of water available to the Elodea will stay the
same level in the 400 cm3 beaker.
Photosynthesis in Elodea Lab Free Short Essay Example
We had learned from the experiment that an Elodea plant in water and pH of 11 solution will grow the fastest under the same conditions of a plant in a pH of 7 and 3.

Photosynthesis in Elodea Lab - Biology Essay Example
My graph has no anomalies, and it closely followed to what I had
predicted that the closer the distance of the light the higher the
rate of photosynthesis would be and thus produce more bubbles in the
Measuring the rate of photosynthesis - Science and …
I can say that the
increase in distance thus making the light intensity stronger
increased the rate of photosynthesis and when further away made the
rate of photosynthesis almost come to its limiting factor the
straitening of the graph.
different methods of measuring the rate of photosynthesis
In our experiment we put baking soda in in our Elodea plant so as the days went by the Elodea plant started losing color and the bubbles started to disappear.

So we chose to do this experiment
After making this choice, we then needed to decide the range of the
input variable (distance from lamp to elodea).

How do pH Levels affect Photosynthesis?
The more acidic pH level the faster the rate of photosynthesis.

What affects the rate of photosynthesis in Elodea? - …
This can be seen on the graph
as the highest point this is where the Elodea is photosynthesizing at
a high rate and it starts to slowly drop as the distance is
