Carbon capture is performed by the green parts of plants via photosynthesis.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
soil moisture (REW).
air humidity (VPD).
air temperature (T).
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of 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.
The rate of respiration decreases with temperature.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in soil temperature.
the changes in light.
the changes in air temperature.
What is the source of carbon that is assimilated in photosynthesis?
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of light.
exposure to excess of CO2.
