Investigation of limiting factors
What this topic asks you to be able to do
- name light intensity, carbon dioxide concentration and temperature as instances of limiting factors in photosynthesis
- explain how altering light intensity, carbon dioxide concentration and temperature affects how quickly photosynthesis proceeds
- describe and conduct investigations that employ redox indicators, including DCPIP and methylene blue, along with a chloroplast suspension, to determine how light intensity and light wavelength influence the rate of photosynthesis
- describe and carry out experiments on whole plants, including aquatic plants, to find out how the rate of photosynthesis is affected by temperature, carbon dioxide concentration and light intensity
