Students are required to know the following;
Students should be able to explain the effects of temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll on the rate of photosynthesis.
Students should be able to:
• measure and calculate rates of photosynthesis
• extract and interpret graphs of photosynthesis rate involving one limiting factor
•plot and draw appropriate graphs selecting appropriate scale for axes
•translate information between graphical and numeric form.

Solve simple algebraic equations.

(HT only) These factors interact and any one of them may be the factor that limits photosynthesis.
(HT only) Students should be able to explain graphs of photosynthesis rate involving two or three factors and decide which is the limiting factor.
(HT only) Students should understand and use inverse proportion – the inverse square law and light intensity in the context of photosynthesis.
(HT only) Limiting factors are important in the economics of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit.

(HT only) WS 1.4
Use data to relate limiting factors to the cost effectiveness of adding heat, light or carbon dioxide to greenhouses.
