To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
air temperature (T).
the total leaf area (LAI).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
Almost half of the total biomass of a tree may be allocated to the roots.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
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.
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
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
