1) Write down the word equation for photosynthesis.
2)
a) What are the 3 main factors that affect the rate of photosynthesis?
b) What does a limiting factor mean?
3) We have the empty graph below with light intensity on the x axis and the rate of photosynthesis on the y axis.

3) We have the empty graph below with light intensity on the x axis and the rate of photosynthesis on the y axis.
a) Draw a line on the graph showing how the rate of photosynthesis changes with light intensity.
b) Out of the start and the end, when is light intensity a limiting factor for photosynthesis?
4) We have the empty graph below with the concentration of carbon dioxide on the x axis and the rate of photosynthesis on the y axis.
b) Out of the start and the end, when is light intensity a limiting factor for photosynthesis?
4) We have the empty graph below with the concentration of carbon dioxide on the x axis and the rate of photosynthesis on the y axis.
a) Draw a line on the graph showing how the rate of photosynthesis changes with the concentration of carbon dioxide.
b) Out of the start and the end, when is the concentration of carbon dioxide a limiting factor for photosynthesis?
5) We have the empty graph below with temperature on the x axis and the rate of photosynthesis on the y axis.
b) Out of the start and the end, when is the concentration of carbon dioxide a limiting factor for photosynthesis?
5) We have the empty graph below with temperature on the x axis and the rate of photosynthesis on the y axis.
a) Draw a line on the graph showing how the rate of photosynthesis changes with temperature.
Try not to use the parts below in this question to help you answer the first part.
b) Explain why the rate of photosynthesis increases when the temperature increases from a very low temperature to the optimal temperature.
c) Explain why the rate of photosynthesis decreases when the temperature becomes greater than the optimal temperature.
6) A plant has a disease which results in it having fewer chloroplasts/ it is unable to produce enough chlorophyll. Comment on how the disease will affect the growth of the plant.
