Limiting Factors in Photosynthesis: Light, CO₂ Concentration, and Temperature
Students will explore the nitrogen and phosphorus cycles, understanding their critical roles in nutrient availability for ecosystems.
Key Questions
- Apply Blackman's law of limiting factors to interpret graphs of net photosynthetic rate against light intensity at different CO₂ concentrations and temperatures, identifying the limiting factor at each region of each curve and explaining the biochemical basis for each limit.
- Design a controlled investigation to determine the effect of CO₂ concentration on the rate of photosynthesis in an aquatic plant, specifying how rate will be measured, how variables will be controlled, and how the compensation point will be determined.
- Evaluate how the light saturation point and CO₂ compensation point are used to optimise growing conditions in commercial greenhouses, and predict how rising atmospheric CO₂ will affect net primary productivity in C3 crops under field conditions.
