Limiting factors of Photosynthesis.
In practice, any one of these factors could limit the rate of photosynthesis.

CO2 + H2O + Light --> Sugar + O2
Students should learn that light is the source of energy used by plants to synthesise sugars rather than as a molecule which is being incorporated to form sugars and oxygen.
Water not mentioned as a limiting factor: textbooks and GCSE syllabuses will often fail to mention water as a limiting factor in photosynthesis
Predicting photosynthesis: Students draw out predicted graphs for light intensity, CO2 level and temperature during a typical day in a named month of the growing season. Explain the shapes of these graphs, bearing in mind effects of respiration. Contrast with an early spring or late autumn day. This will lead on to the topic of and is suitable for students of higher level
Presentation: Create a presentation on how to grow a plant in the best possible conditions. Students must make a reference to each limiting factor as well as any additional knowledge that they might have. Presentations may talk about fertilisers, which relates to the topic . Suitable for students of all levels
Activity: Students try and design a way to grow crops for a manned moon-base. They will essentially create a greenhouse which can provide a suitable amount of each limiting factor required for photosynthesis. Students may even add additional features to their "space farm". Suitable for students of lower level and SEN
Photosynthesis Limiting Factors by bobfrazzle - …
How have humans overcome limiting factors? This ties in heavily with "Food and the environment" and would serve as a good question to link the students' concepts of photosynthesis to large scale agriculture.

Limiting factors of Photosynthesis. by liam scoble on …
This topic will outline how the rate of photosynthesis can be reduced and inversely how we can increase the growth of a plant by addressing these limiting factors.
After learning about the photosynthesis process students will learn about how the rate of photosynthesis can be reduced by lowering the availability of a limiting factor.
Students of all examination boards are expected to:

Limiting Factors In Photosynthesis
Students can be asked to interpret graphs showing photosynthesis where two limiting factors are kept constant and one limiting factor is slowly increased. Students must know why the rate of photosynthesis decreases or increases on the graph.
Limiting Factors of Photosynthesis - Get Revising
Farmers use methods such as burning methane/oil-fired heaters in greenhouses to increase levels of CO2 because enhanced levels of CO2 will increase the rate of photosynthesis, provided that no other factor is limiting the process.
