4.4.1.2 Rate of Photosynthesis — AQA Combined Science Trilogy 8464

Explain the effects of temperature, light intensity, carbon dioxide concentration, and chlorophyll levels on the rate of photosynthesis.
Measure and calculate the rates of photosynthesis using appropriate methods.
Extract, interpret, and plot data on graphs to represent photosynthesis rates, ensuring appropriate scales and axes are used.
Translate information regarding photosynthesis between graphical and numeric formats.
(HT only) Understand that limiting factors interact and identify which factor limits the rate of photosynthesis in given scenarios.
(HT only) Explain graphs that involve two or three interacting limiting factors.
(HT only) Apply the concept of inverse proportion, specifically the inverse square law, to light intensity in the context of photosynthesis.
(HT only) Evaluate the economic importance of controlling limiting factors in greenhouse environments to maximise photosynthesis rates and profit.
Plan and carry out a practical investigation into the effect of light intensity on the rate of photosynthesis using an aquatic organism.
