Rate of photosynthesis

HideShow resource information
How can the rate of photosynthesis be measured?
1. Increase in biomass 2. Production of oxygen 3. Uptake of CO2
1 of 8
What is responsible for the decrease in the rate of photosynthesis in relation to temperature?
The decrease in the rate of photosynthesis is due to the denaturation of enzymes involved in the chemical reaction of photosynthesis.
2 of 8
Where do the absorption & action spectrums peak?
In the red & violet-blue regions
3 of 8
What are 3 factors that influence the rate of photosynthesis?
1. Concentration of CO2 2. Light intensity 3. Temperature
4 of 8
Which region on the absorption/action spectrum has the least absorption?
The green region.
5 of 8
What are the ways that photosynthesis can be measured experimentally?
1. Counting oxygen bubbles 2. Using a syringe to collect volumes of oxygen produced 3. Testing the pH of the water
6 of 8
What is responsible for the effect of temperature on the rate of photosynthesis?
The effect of temperature on the rate of photosynthesis is due to the involvement of enzymes in the process of photosynthesis
7 of 8
In reference to the absorption of light, what is the rate of photosynthesis influenced by?
The rate of photosynthesis is influenced by the extent of absorption of light of different wavelengths by the pigments.
