Transpiration decreases as air becomes drier.
The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
As plants respire, they release
Photosynthesis of a tree canopy is driven or influenced by
photosynthetically active solar radiation (PAR).

air humidity (VPD).
The rate of respiration decreases with temperature.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Carbon capture is performed by the green parts of plants via photosynthesis.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Plants open its stomata to avoid losing too much water.

To transform atmospheric CO2 into organic molecules, plants can use the energy from
Almost half of the total biomass of a tree may be allocated to the roots.
