Revise: Limiting Factors and Greenhouse ConditionsAt low light intensity, increasing the intensity increases the rate of photosynthesis because more light energy is available. If other conditions remain unchanged, the rate eventually levels off: supplying still more light no longer increases photosynthesis.
- Revise: Investigating Light Intensity and Measuring Photosynthesis
The amount of photosynthesis occurring per unit time, estimated experimentally by oxygen production per unit time.
