Factors affecting photosynthesis
Biology · Secondary 4 · Hard · Factors affecting photosynthesis
A plant is placed in bright light but with very little carbon dioxide available. How will the rate of photosynthesis be affected, and why?
- The rate stays low because carbon dioxide concentration is the limiting factor.
- The rate becomes zero because light is no longer needed for photosynthesis.
- The rate becomes very high because light intensity is the only limiting factor.
- The rate increases steadily because chlorophyll is produced only in low carbon dioxide.
