Carbon becomes locked as part of the accumulating plant biomass as plants grow.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Carbon capture is performed by the green parts of plants via photosynthesis.
The rate of respiration decreases with temperature.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air humidity (VPD).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
air temperature (T).
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
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.
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.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of CO2.
exposure to excess of light.
exposure to shortage of soil moisture.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
In some part of the stems, some photosynthesis may also occur.
