5A- Limiting Factors In Photosynthesis

Question 1

What are the optimum conditions for photosynthesis?

Answer 1

High intensity of certain light waves
-Light is needed to provide energy, the higher the intensity, the more energy. (Red and blue).

Temperature around 25C
-Photosynthesis involves enzymes. If the temperature falls below 10C the enzymes become inactive, but if it’s more than 45c denature occurs.

Carbon dioxide at 0.4%
- In the atmosphere it’s 0.04%, if you increase it to 0.4 it gives a higher rate of photosynthesis, but any higher and the stomata starts to close.

Also needs a constant supply of water.
