Investigating the Effect of Light Intensity on Oxygen Production in an Aquatic Plant.

Extracts from this document...

Introduction

BIOLOGY COURSEWORK Investigating the Effect of Light Intensity on Oxygen Production in an Aquatic Plant. Analysis. The results in the table below show the results of an experiment investigating the change of light intensity on the production of oxygen in an aquatic plant, Elodea. Distance from Lamp (cm) Number of Bubbles per Minute 100 6 60 10 40 18 30 24 20 25 On the following page is the graph I drew of the above results. ...read more.

Middle

The gradients show the rate of reaction in each section, between two distances. m = gradient m = change in y-values change in x-values A) m = 4 (number of bubbles per min) 13 (cm) m = 0.31 bubbles per min/cm B) m = 4 (number of bubbles per min) 7 (cm) m = 0.57 bubbles per min/cm C) ...read more.

Conclusion

The findings show that as the distance from the lamp was further away from the Elodea, the number of bubbles produced was less. The further the lamp was from the plant, the less it could photosynthesis and produce oxygen. So as light intensity increased the rate of photosynthesis increased, and is limiting the rate of the reaction. ...read more.

    Keep the lighting in the room the same throughout each experiment by shutting blinds, turn of lights. * Time the experiment. Count the number of bubbles produced by the plant within a certain amount of time, alternatively you could time how long it takes for the plant to produce a certain amount of bubbles (e.g.

    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
