To transform atmospheric CO2 into organic molecules, plants can use the energy from
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Transpiration decreases as air becomes drier.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
In some part of the stems, some photosynthesis may also occur.
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.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air temperature (T).
photosynthetically active solar radiation (PAR).
soil moisture (REW).
air humidity (VPD).
The rate of respiration decreases with temperature.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
