In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Carbon capture is performed by the green parts of plants via photosynthesis.
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Photosynthesis of a tree canopy is driven or influenced by
photosynthetically active solar radiation (PAR).
air temperature (T).
the total leaf area (LAI).
air humidity (VPD).
soil moisture (REW).
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in air temperature.
the changes in light.
the changes in soil temperature.
In some part of the stems, some photosynthesis may also occur.
Almost half of the total biomass of a tree may be allocated to the roots.
Transpiration decreases as air becomes drier.
The rate of respiration decreases with temperature.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
