light. Bright light is a basic element of photosynthesis, but variations in the color of light have an effect on plants. The entire spectrum of light hits the plant's leaves at the same time, but there are some colors that are known to cause higher amounts of photosynthesis than others. Chlorophyll is the cause of each plant's individual coloring and there are four kinds of pigments that create the chlorophyll. They are called Chlorophyll A, Chlorophyll B, Xanthophyll, and Carotene. Some leaves have more of a certain color pigment than they have of others, creating leaves that are bright green, blue-green, yellow-green or even orange or red. This pigmentation makes no difference with photosynthesis.


Humidity
The effect of humidity on the rate of photosynthesis in a plant is very similar to that of water. If there is a lot of humidity in the air around the plant, less water from the plant evaporates. This allows the plant to open its stoma wider because there is no risk of losing excessive amounts of water. Because of this, the rate of photosynthesis increases as the humidity increases. Another factor of the humidity in the air is that the ground can be more moist, so the plant's roots can extract more water from the ground.

This diagram looks at the 3 (main) factors that effect the rate of photosynthesis as a whole.

It was hypothesized that since sub-stomatal carbon dioxide concentrations are often saturating to photosynthesis at ambient external concentrations in C4 plants at high light, photosynthesis might be insensitive to partial stomatal closure caused by large leaf-air water vapor pressure difference. The response of stomatal conductance and photosynthesis at high irradiance to vapor pressure difference was determined under uniform conditions in C4 plants grown under controlled conditions, and outdoors. In several cases, photosynthesis was less sensitive to stomatal closure than it would have been if photosynthesis had a linear response to sub-stomatal carbon dioxide concentration.

PH acidic
The pH level effects the productivity throught the enzymes in the plant cells. At certain pH levels the enzymes in the plant can either denature, stop working or slow down; they would no longer carry out chemical reactions in the cell to their full pontential, including photosynthesis. Therefore as the plant's pH drifts away from the median pH the photosynthesis production will decrease.

hope this helps u
