PDF Lab Photosynthesis
Light and rates of photosynthesis In today's lab, you will be designing an experiment to test the effects of light on photosynthesis. There are a number of possible ways these effects can be explored. Transmittance. Colored filters can be used to control the wavelengths of light that the algae receive.
PDF Investigation into the effect of light on the rate of photosynthesis
• Instead of placing vials at different distances, light intensity may be varied by covering the vials with neutral density filters and maintaining the same distance from the lamp. In this way, any potential heating effect has a consistent effect. • Vials may be covered with colouredfilters to expose the algae to different wavelengths.
PDF Experiment #5: Photosynthesis
The rate of photosynthesis increases linearly with increasing light intensity. Gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant. After that point, the rise in light intensity has no effect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting.
PDF Investigating Photosynthesis
3x the distance gives = of the light intensity 10 x the distance gives = of the light intensity Neutral density filters Neutral density filters are grey-coloured. They reduce the amount of light passing through them across the spectrum (in the 400-680nm range). They can be used singly or combined with one another to investigate the effect of ...
PDF Investigating the effect of light colour on the rate of photosynthesis
The overall chemical reaction involved in photosynthesis is: 12H2O + 6CO2 (+ light energy) → 6O2 + C6H12O6 + 6H2O Aim: To investigate the effect of light colour on the rate of photosynthesis. Hypothesis: It is hypothesised that in this experiment, photosynthesis would occur at different rates depending on the colour of the wavelength.
PDF The effects of Light Intensity on the Rate of Photosynthesis of Aquatic
Using "Borderless Lab 365", to investigate the effect of light intensities (dark and light) on aquatic plants' rate of photosynthesis. Theory Photosynthesis process: Aquatic plants carry out photosynthesis during daytime and respiration during night time. Photosynthesis is the process where plants absorb carbon
PDF Photosynthesis Virtual Lab
1. Write a problem question to test effect of light intensity. 2. Write a hypothesis for the relationship between light intensity and photosynthesis rate (as measured by ATP production in the light dependent reaction). 3. Design and run an experiment to test the effect of light intensity on photosynthesis. Be sure to keep the wavelengths
PDF Lab 5. Photosynthesis: Why Do Temperature and Light Intensity Affect
affect how quickly photosynthesis takes place within a plant. You will then develop a conceptual model that explains why. Your Task Design a series of experiments to determine how temperature and light intensity affect the rate of photosynthesis in spinach. Then develop a conceptual model that explains why these environmen-tal factors affect ...
PDF Measurement of limiting factors in photosynthesis
l, (B) effect of light intensity at 25 Light intensity does not fall linearly as the samples are moved away from the lamp. The Figure 1 Effect of external factors on the rate of photo-synthesis in chlorella: (A) effect of light intensity at 25 °C and 0.04% CO 2 °C and 0.01% CO 2; adapted from Hall and Rao (1999)

present and future research. The role of photosynthesis as a source of food and fuel is highlighted. The student is also encouraged to think practically with a useful chapter on simple laboratory experiments. The book will appeal to students and teachers of biology from those doing A-levels to undergraduate degrees.
