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