Factors affecting photosynthesis
Biology · Secondary 4 · Medium · Factors affecting photosynthesis
A student measures the rate of photosynthesis of a water plant at different light intensities while keeping temperature and carbon dioxide concentration constant.
At low light intensity, increasing light causes a large increase in rate. At high light intensity, further increases cause little change.
What is the limiting factor at high light intensity?
At low light intensity, increasing light causes a large increase in rate. At high light intensity, further increases cause little change.
What is the limiting factor at high light intensity?
- Carbon dioxide concentration
- Light intensity
- Chlorophyll amount
- Water potential of the soil
