Cellular Respiration Lab Report

This is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of oxygen bubbles). We will determine whether or not it is possible to examine the relationship between photosynthesis and cellular respiration under controlled environmental conditions.

We will show the effects, reactions, and relationship between photosynthesis and respiration, as well as demonstrate to you how the scientific method works. Hypothesis Upon completion of the investigation we will be able to determine if gas that will be produced with the intensity of light at different wattages.

Materials and Methods The following methods were used to calculate the rate of photosynthesis: Measuring the uptake of CO, measuring the production of carbohydrates, and measuring the increase in dry mass.

We will also measure the production of 02 the experiment in the experiment. Oxygen can be measured by counting the bubbles evolved from seaweed to measure the amount of gas produced by four different light intensities (25, 50, 75, and 100) measuring each different light intensities times three.

Results or Outcome was able to determine the amount of gas produced by the four different light intensities. The more light, the faster the rate of photosynthesis. However, increased rate o photosynthesis only goes to a certain point.

You would think hat the more intense the light the higher the rate, but there us a certain limit. Table 1: Rate of Photosynthesis Measured by the Number of Oxygen Bubbles Light Bulb Trial 1 Trial 2 Trial 3 Average O watts 2 3 25 watts 7 4 5 50 watts 11 100 watts 12 13 Conclusion In conclusion, the outcome of this experiment was what I expected it to be.

What I did not expect is when the intensity of light increased the rate of the photosynthesis only went up to a certain point. Assumed the more light the more photosynthesis, this investigation showed me differently.
