1. Light INTENSITY
In dim light, the rate of photosynthesis is slow.
As light intensity increases, the rate of photosynthesis increases until a certain point.
At high light intensities, temperature is usually increased too, which can cause enzyme denature.
Leaves can reduce this by folding leaves.

2. Temperature
At cold temperatures, photosynthesis is reduced.
At warmer temperatures, photosynthesis speeds up. Too hot, however, and the enzymes denature and photosynthesis stops.

3. CO2 Amount
As CO2 concentration increases, so too does the rate of photosynthesis (refer to equation)
4. Water supply
If water loss is too great, the leaves will close their stomata to conserve water. This poses another problem though.
With the stomata closed, CO2 diffusion will not occur and photosynthesis will be reduced.
